How To Check and Fix Your Onan 6.5 Generator

Onan 6.5 generator would certainly quit following 20 mins or so. When I attempted to begin it once again, the poer cell would certainly not start back up. However, if I waited a little while, it would certainly start again with no trouble. My limited mechanical knowledge led me to think that the trouble was gas associated.

After doing some research I was able to figure out that the trouble was a bad gas filter. To be sure I examined the gas pump using a straightforward examination I review online. The test assisted me to detect and also fix this issue. In this article, I’ll discuss exactly how to execute this test on your Onan Recreational Vehicle alternator if you’re having a comparable problem.

Why Not A Bad Carburetor Or Gas Filter?

When cool, the alternator would start up and run smoothly for around 20 mins. If I allow it rest for a while, the alternator would start back up as well as a run fine for one more 20 mins. This was pretty consistent behavior. This told me that the carburetor needs to be great.

If the carburetor misbehaved, I think the alternator would not begin in all, or possibly begin, run rough as well as quit.

If you’re stating to yourself “what concerning the fuel filter?” Well, I figured a bad or stopped up gas filter would create the alternator to run poorly regularly. So it was ruled out too.

When I suspected the offender to be a malfunctioning gas pump, I wanted to examine it before buying any type of component. Testing the gas pump became pretty easy. The secret was when to run the test?

When To Check The Fuel Pump

I suspected that the fuel pump would operate just great if checked when the alternator is cooled. So I decided to do the gas pump examination after the powercell dies. That was my plan.

I launched the power cell and awaited it to die. Certainly, it passed away after around 20 mins. That’s when I tested the fuel pump. Guess what? It fell short.

How To Examine The Gas Pump

Run this test promptly after the alternator passes away . The test will certainly inform you whether the fuel is being pumped to the carburetor during that time. All you’ll require is a bucket and also screw motorist to do the test. Heres’ exactly how:

Separate the fuel hose going into the carburetor (make use of the screwdriver to loosen the hose clamp).

Checking Onan power cell fuel pump and filter.

Point the hose pipe right into the container.

Press the alternator to begin or prime button (press left the side of begin switch).

You ought to obtain a good flow of gas into the pail if the gas pump is functioning. If not, you’ll obtain a trickle or absolutely nothing.

Evaluating Onan alternator gas pump and filter.

If no fuel comes out, purchase a brand-new gas pump since it’s likely negative (possibly overheated). I had no fuel coming out when I ran this test on my alternator.

Connect the gas hose pipe back on the carburetor.

Where To Get A New Fuel Pump.

You could get one from an Onan dealer I suppose. I got my replacement fuel pump from Amazon.com. The parts you’ll require for this repair are in this Onan repair service components list I produced for you. It consists of the fuel pump and filter as well as a few other typical replacement components.

Simply click on each product to get even more information.

Keep in mind: I suggest you purchase a new Onan gas filter and also change it when you replace the gas pump. It’s the only time you’ll have the ability to access it anyway.

Devices You’ll Need.

Before replacing the fuel pump, make sure you have these tools on hand.

Changing the Onan alternator gas pump as well as the filter.

T-30 TORX socket to eliminate the TORX screws holding the control board as well as various other stuff (this alternator has numerous T-30 TORX screws).

Vice Grips to pinch the inbound fuel line from the gas tank.

A bucket or drip frying pan to place under the pinched gas line in case it leakages.

1/2 inch outlet or wrench to remove the solenoid or grounding bolt.

How To Replace The Gas Pump.

Changing your power cell fuel pump and filter is a DIY task that you can execute. I’m not a technician and replaced the fuel pump and gas filter on my alternator without any difficulty. The most difficult component was eliminating everything just to get to the fuel pump.

Replacing the alternator fuel pump and also filter.

The gas pump is located behind and below a lot of things on the left side of the alternator area. To reach it, you’ll need to eliminate everything on top as well as in front of it. I suggest taking a photo of the location with your mobile phone to help you when you put whatever back.

Onan 6.5 gas pump and also filter.

Below’s a quick rundown of just how I changed the fuel pump and also filter.

Disconnect your Motor Home from coast power.

Separate the unfavorable wire from your Recreational Vehicle battery.

Squeeze the gas line between the gas tank and fuel filter (connected to the gas pump) to make sure that no gas streams when you separate the tube.

Area a drip frying pan below the left rear of the alternator where the gas pump lies to catch any type of fuel that runs out.

Detach the gas hose from both ends of the gas pump as well as the gas filter (the drip pan ought to capture any type of gas that trickles out).

Eliminate every little thing obstructing access to the fuel pump (control board, solenoid, cables).

Eliminate the bolts holding the fuel pump as well as eliminate the gas pump and also filter.

Screw the new gas filter into the new fuel pump and also screw it in position.

Affix the gas lines to the brand-new gas pump/filter.

Place every one of the various other stuff you eliminated back in reverse order.

Get rid of the vice grips from the gas line as well as look for leaks.

Do a fast inspection to see if whatever is put back together as well as connected.

Reconnect power to your battery and coast power (if necessary).

That’s it. You’re ready to check your fix.

Examination The Power Cell.

Left press the alternator begins button as well as quiet for a couple of seconds to prime the pump. After that press the appropriate side of the beginning button to discharge up the alternator. It needs to terminate right up.

If you’ve done whatever right, your alternator will run and also run as well as run. When it warms up, turn on a few things to place a load on it and also let it run. Success!

Any type of kind of encased camper with wheels, used for fun or getting away a normal lifestyle, can be called an RV, or Rv. Usually, though, the term “Mobile home” is utilized to describe an A, B or C-Class recreational vehicle. Travel trailers that are lugged in addition to camper tops that are attached to pick-up beds do not normally have generators fitted by the manufacturer. An as well as also C-Class Recreational vehicles typically do, and additionally, B-Class Recreational vehicles generally have a product bay preconfigured to have one fitted as a choice. Wiring an alternator that is manufacturer-installed, or set up right into a alterantor-ready bay, is a straightforward job.

Step 1

Set up the circuitry harness which enables the alterantor to work. Choose whether a remote button to start and additionally quit the alternator is necessary, or whether making use of the turn on the generator’s fascia will certainly be adequate. If a remote starter/stop-run switch is asked for, run a twin-core 14-gauge wire from the alternator to the area of the switch, as well as attach a rocker switch according to the switch manufacturer’s guidelines. Discouraging the top of the rocker button will activate the alternator to begin; the disheartening the lowest level of the rocker button will produce the alternator to stop. The switch will go back to a main, non-functional setup when not depressed. Attach the twin-core cable to the terminals on the alternator control board, which will be significant, making use of spade ports.

Activity 2

Mount the electric wiring harness which permits the alternator to function without a remote starter center by attaching an on the internet cable straight to the power cell control panel. Commonly the generator’s ground will certainly be made via its places to the Rv’s structure. Observe Onan’s configuration guidelines for the live wire, which will typically be linked to a threaded captive bolt. If this holds, attach an eyelet terminal throughout the wire from the specialized battery, as well as secure it in position on the threaded slave nut using a lock washer, a conventional washing machine and afterward a bolt. Starter separate, gas pump control and also electrical choke control will certainly all be automated.

Action 3

Set up the circuitry harness which moves electric power from the alternator to the Mobile home. Run a cable from the area of the alternator to the within the products bay alloted for the storage area of the coastline power cable. Usage type-UF cable ranked for the amperage created by your power cell. At the alternator end link, the real-time cable television to a clearly-marked protected threaded hostage screw using an eyelet incurable protected in position on the threaded hostage nut making use of a lock cleaning equipment, a standard cleaning machine and afterward a screw. Link the negative cord to the negative terminal in the same design, and also the planet cable to the earth terminal in the same style. At the end of the cargo bay web link, the cable to an electric outlet suggested for the amperage need of your Motor Home as well as the matching amperage distribution of your alternator, either 30 or 50 amps. Meticulously observe the electrical outlet manufacturer’s guidelines connecting to polarity.

Establish a starter battery committed to the alternator, so starting power does not rely on and/or erase the instructor or structure batteries of the Mobile home. Wired correctly, the battery will be billed by the running alternator, equally as the framework battery is charged by the framework engine. Speak to the alternator manufacturer’s compositions worrying battery capacity; usually, a ride-on lawnmower battery will carry out suitably. Situate the battery where it will certainly not be subject to excess heat or undampened resonance. Fit it in an exclusive battery tray, and additionally protect it in place with the band or metal hold included with the tray. Use black color-coded 6-gauge wire to attach the undesirable incurable to ground, and also use the red color-coded 6-gauge cord to affix the favorable terminal to the significant terminal on the alternator, normally on or near the starter electrical motor.
