The Recreational Vehicle generator, a vital element in a motorhome’s electric system, provides 120-volt-AC power (or, depending on the design, 120/240-volt AC power) for completely dry camping or when the coach is being driven. Onan, a product line of Cummins Power Generation, is one of the most prominent brand names of Recreational Vehicle alternator.

This post focuses on the procedures essential to service power cells in the Cummins Onan Quiet (QD) Series, with an emphasis on the servicing treatments for larger models (10 kilowatts as well as 12.5 kilowatts). Even within the Cummins Onan line of product, service periods, as well as treatments, vary depending on the alternator size as well as a day of manufacture; while several of the basics might put on other alternator brand names as well as models, make sure to check the proprietor’s handbook for details guidelines.

The RV diesel generator is housed in a sound-deadening enclosure and can be installed to a slide-rail system, which enables the power cell to be expanded from the front cap for easy accessibility. Depending upon the year as well as design, a Cummins Onan QD alternator might be furnished with either an Isuzu or a Kubota water-cooled motor, which are among one of the most trustworthy in the sector. The engine is straight combined to the power cell, unlike belt-driven devices discovered in numerous gasoline-powered generators.

A Rv Diesel alternator could be what you are looking for. A four-pole alternator normally should be run at 1,800 rpm to give 60 hertz of power, however, the smaller sizes make use of inverter modern technology to permit a variable-speed procedure that elevates the engine rpm as the lots increases. Bigger power cells– 10-kilowatt or 12.5-kilowatt– do not make use of inverter innovation; they run at a constant controlled 1,800 rpm regardless of just how much lots is applied.

Operation Switchover

The Cummins Onan QD alternator has a procedure to activate its unit. A second remote switch typically is placed inside the trainer. Holding the button in the “Run” position activates the glow connects to preheat the engine. The switch may have to be held a few secs before the engine will certainly crank. This is typical; the time differs relying on exactly how chilly the ambient temperature level is. As soon as the radiance plugs have warmed the engine sufficiently, the starter involves cranking the engine. And also once the engine starts, the button can be released. Most buttons have a red pilot burner that lights up when the alternator is running. To quit the power cell, hold the button to the “Quit” setting for a second or 2.

If a power cell runs out of gas or its gas filter is changed, the unit will not start without very first priming the fuel system to hemorrhage out the air. Hold the procedure switch at the “Stop” placement and also proceed holding it. Sometimes, you may be able to listen to the alternator’s electric fuel pump run, however, regardless, the red pilot light will light up. Launch the operation button after 30 secs; the gas system should be primed. If the power cell fails to start, duplicate this treatment. Keep in mind that this treatment can be performed at the alternator or the remote switch in the motorhome.

Extensive Diagnostics

Cummins Onan QD alternators include substantial diagnostics to detect system mistakes, which are presented as well as gotten from the condition light on the operation button. When the light flashes as soon as, then relaxes and repeats, it shows a shutdown because of the high engine coolant temperature level. If the light flashes twice, relaxes, and repeats, it indicates a reduced oil stress fault. When the light flashes three times, rests, and also repeats, it shows a service fault; because case, a 2nd step is needed to get the details fault code.

To obtain a solution mistake code, you might first need to wake up the control by pressing and holding the “Quit” button. Then touch the “Stop” button as soon as. This shows a two-digit solution code, which includes two collections of flashes. The initial set of flashes represents the first number of the code; after a pause, the 2nd set of flashes suggests the code’s 2nd number. After a long pause, the sequence repeats. For instance, fault code 36 appears as blink-blink-blink– pause– blink-blink-blink-blink-blink-blink. Press the “Stop” button to stop the blinking code. A total checklist of fault codes appears in the back of the driver’s guidebook or can be located online in the Cummins Onan Motor Home Manual, www.goo.gl/IY2Vpz.

A great prestart checklist begins with prolonging the alternator slide as well as removing the side gain access to cover. Then check the engine oil level and also look quickly for anything misplaced, such as fuel or coolant leaks. (Note: On the 6-kilowatt as well as 8-kilowatt Cummins Onan QD alternators, the oil is examined using the dipstick near the stop/start switch.) Undoubtedly, if you are driving as well as decide to use the trainer’s air conditioning system, you will not make these checks right after that, but don’t ignore them. Make it component of your regular to check the alternators frequently at a camping area, depending on just how typically it has been made use of.

Refer to the power cell’s solution routine to see what is needed, and afterward, get the correct filters as well as liquids. If components should be gotten, the alternator version number and spec modification will be required. This detail appears on a placard placed to the machine near its circuit breaker and primary procedure switch. The placard additionally indicates the oil ability of the crankcase in addition to Cummins Onan component numbers for the most common filters.

Common Solution Period

One of the most typical solution intervals is 250 hours or one year, whichever precedes. It contains a fundamental engine oil as well as filter adjustment. Servicing of gas, as well as air filters, comes at 500 hrs or two-year periods. Nonetheless, a brand-new power cell requires oil and also filter adjustments after 50 hrs to get rid of impurities from the oil throughout the engine’s burglary period. Refer to the driver’s manual for the certain needs of your alternator design.

Engine Oil And Filter

To change the oil and oil filter, a 7/8-inch socket and cog, a drainpipe pan, and also an oil filter wrench is needed. A pair of rubber handwear covers and some cloths or disposable store towels additionally can be found in handy. Cummins Onan alternators are understood for having very limited oil drainpipe lugs when they leave the factory. To loosen the drain plug the first time, use a huge breaker bar, perhaps with a pipe for even more utilize. Several proprietors also find that the manufacturing facility has installed a smaller-diameter oil filter; do not fret about the difference in dimension in between the preliminary burglary filter and also the replacement. However, your oil filter wrench may not fit the smaller filter, so a big pair of channel-lock pliers or some other device may be required to eliminate that filter.

Run it long enough to heat the oil and also permit it to stream via the system. This will certainly make sure that any type of sludge is liquified as well as suspended in the hot oil. Shut down the engine and also turn off the breaker on the power cell. Likewise make sure to disengage the Automatic alternator Start component if the motorhome is equipped with one, to make sure that it can not begin the alternator during service. When whatever is set, prolong the power cell and also eliminate the solution gain access to cover from the chauffeur’s side of the alternator, if you haven’t already.
