MEP 802A DS6 and DS7 not working

[319cssb]

These two lights never worked on my 802. When I close the Contactor it wont come on. The battle switch doesn't light up when its switched.
The test when pushing on the LED doesnt work. I swapped the LED's with those known to be working. and they stopped in this generator. the lights I removed work in the other generator.

I've been probing a bit around and I have voltage at the R15 resistor and behind the diode as well. I don't have continuity from R15 to TB6-6 . If I am reading the schematics correctly , then I should have continuity from R15 to the center tab of DS6 (pin 1) and consequently to the center tab of DS7 (pin 1).
It would be good to have these two lights, just to know have a feedback from closing the contactor S5. The Battle short is obvious when its on, but a visual feedback would be cool, especially since its its there.

If you have 24VDC to R15-1, then just test the following places. Continuity test are not a good test. Try and always test voltage. Continuity can lie to you.


TB5-12 Wire #137E to R15-1
R15-2 Wire # 111C to TB6-6
TB6-6 wire # 111B to DS6-1

TB5-12 Wire #137E to R15-1 =0v
R15-2 Wire # 111C to TB6-6 =0v
TB6-6 wire # 111B to DS6-1 =0v

Diagnosis : got the wiring mystery figured out. Some stupid reversed wiring on R15 and R14 137b and 151a.
now I need a new green and red led for DS6 and DS7

oh and when I said I had 24v at the resistor. Due to the way the board is labeled , I took the voltage off of the wrong part

You have voltages now, correct? Only issue is the red and green LED bulbs. Right?

That’s correct .

Super Cool! Just Google the lamp info on the lamp and parts manual. Not too expensive. I have to say, I have never seen one burn out. Made bad all the time, but burn out no.
