Default Cummins 100 KW DGDB Diesel genset

All,
I was hopefull to tap into the knowledge here.

At one of my jobs they just got this used Cummins/Onan 100 KW DJDB diesel genset. It has the Cummins inline 6 (6bt engine) in it. I had to install new batteries (24 volt) and a new fuel line, otherwise its running great.

One problem, with the switch in the "Off" position, you can clear a clicking in the control box. Sounds like a relay click on and off, about every 2 seconds. If you put the switch in the remote position, the clicking stops.

Any idea what that cause of the clicking could be?
I am fairly familiar with the older Onan wiring, but these new ones, are similar but different

I should have the service manual. Being in off should clear the control system. Can you put your hand on anything while it clicks. You might find what is causing the problem.

Tony:

The controller on that genset is referred to as a 12 light control.

In the "Off" position the "Not in Auto" light should be flashing.

The click you hear is the flasher relay. If you don't see the light flashing, bulb is burned out. Hit the "Lamp Test" switch and see how many more of the are out.

Cummins is real proud of those bulbs.

Thanks Gunny. Guess I have been out of the trade to long. Completely forgot about that. If I remember correctly They went to a higher voltage bulb to make them last longer. I know I got tired of changing the things every time I checked one.

Billy: They made those bulb in 12, 14 24, 28 and 56 volt. Some, like the ones in the ATSs (normal available and connected) seemed to burn out once a week or so, emergency available and connected would last forever. I modified a bunch with a LED, they appeared to have a long and happy life.

The 12 volt ones get real bright if you apply 24 volts but not as bright as what 56 did to them. Don't run long either. Make your eye blink and see blue dots everywhere for an hour or so.

All the different variations of the 12 Light Control, some had as many as 18 lights, plenty of spares for a few years. Use the unused ones to replace the ones that burn out, or the ones an engineer spec'd but never used.

Really liked that 12 Light, in my opinion, for what its worth, the best controller Onan ever built. Easy to work on until they put that relay board over top of it.

I will go back and check to see if I can figure out which relay is clicking.

I did a quick Lamp check, and I thought all of the lamps lit up, but I will double check.
I will also look and see if there is a "not in auto" lamp on the control panel.

The light really is burned out

The easy solution, is to keep it in 'remote' when it's not needed. These sets were made for standby service, so it's as important to make sure there is a warning/alarm when the set is disabled as it is to have warnings for overtemp or low oil pressure-they both have the same effect, the lights stay out and your phone rings at 2am!!

Its supposed to click if not in auto. The important light on a 7 or 12 light is the green run light. If it comes on in test, the bulb is good, if the bulb is good and it does not come on when the genset is running, either you have no AC output or the alternator is not charging. Then you don't have one of the start disconnects.

If, by chance, this genset is a Detector 7-Light, and the A11 control board has been replaced, you will hear the clicking when not in auto, but, with the 7-light there is no Not In Auto lamp. All Detector boards are replaced by the current production 12-light board. So, with 7 lights, clicking, but no lamp.

OK, you were all correct. I checked the bulbs again, the bulb labeled "SWITCH OFF" is burned out.

Now, does anyone know of a replacement? (other then Cummins???)

There are a lot of numbers close on this bulbs but you would have to talk with them tomorrow to see if any would work http://www.srsales.com/ it didn't pull up my inventory check but I copied it to my email if you give me your email i will send it to you pm or post it

I think I may have found the replacement bulb here
http://www.bulbtown.com/2176_MINIATU...ASE_p/2176.htm
or here
http://www.bulbtown.com/6838_MINIATU...ASE_p/6838.htm
I would have to wire the bulb into the socket, but that is easily doable with a solder gun.
Also, I found them Ebay, $8 each + $5 shipping.
Still looking for an LED replacement though

Leds are easy, Led + Resistor. Depending on color (red/amber/green etc, and current desired) your resistor will vary. Super- bright/HO units only pull 20-30 mA (.02-.03Amp). Start w/ the basics: what size hole does it need to fit into? 1/4 - 5/16 - 3/8 - 1/2" sealed snap in assm`s are common. How bright do you want? If you want, PM me a # and a time to call and I`ll help you out. I do complete custom led dashs and tailights, at any given time I have 2-3000 led`s in stock, and handfulls of resistors... Toss on some heatshrink and you re good to go! Upside: 5000 hr+ life expectancy and no filament/vibration issues!

Yall know Onan did not invent the electric light? Don't even have a factory that makes them

http://www.mouser.com/ProductDetail/...2OFch1TJQTo%3d

These come with the lenses. The white lens was cheapest, you can just snap the lens off. If you need another voltage and/or color this link will get you close.

There is tons of room in this housing for a resistor and a LED as well, but at that price it's not so painfull to replace the burned out ones immediately and then convert the dead ones to LED for future use.

They did burn fast. I replaced one did my inspection and replaced the same one again before I left.

Put a lot of funds in someones pocket. If I remember they were something like $14.00 or so each. Think you could also buy the bulb, no lens for a little less.

If you solder in a LED, remember they are polarity sensitive.

Think the ones in the ATS went out faster, AC kills them faster than DC does. Keep that in mind if you go to make up some LED bulbs for your ATS. Those are 24VAC, except for the real old ones that are 56VAC.

I don't know but I suspect the bulbs that burn out faster, are being run at higher voltages than they are rated for.
Also the filaments in some light bulds have more mechanical supports than others, vibration issues. In cars some bulbs have none others have 5 supports. Just like rough service bulbs in trouble lights (120V 75Watt types)

IF you look at bulb with magnifing glass you can see them.
