I have been trying to bring back an Applied Companies Drash unit and am starting to get a little deeper than I like and thought I would reach out and see if you guys have experienced this stuff before.
I knew the fuel pump was bad on the Perkins when I got it so I pulled it and had it rebuilt. I had a crack in one of the hard return lines but repaired it and it is now fine too. I am now already pretty deep into this from a money standpoint just from that stuff. With the new pump the engine starts and runs fine. No matter what the electronics are doing it does not surge, hunt or fluctuate RPMs it just purrs like a kitten.
The issues start however as soon as it is started with the 4PDT relay which starts buzzing immediately on start-up regardless of switch positions etc...and the 'low fuel or stopped' LED is flashing. I have spent time in the manuals and schematics and this means the Generator has no voltage on Phase B (though the buzzing to me is not correct as it should be on or off, not buzzing between the two.) So the obvious thing to check would be the breakers on the inside of the cabinet for the generator but they are fine. I kinda want to focus on this first since I think this may be causing other issues too. I think there is a short somewhere but not sure where to start.
The generator LEDs have shown a Green LED for proper RPM and some times a Red one for Low RPM. This is likely because I dont sense that there is any electronic speed control being done if that helps? If it starts and mechanically the RPM is right, it stays there. If the RPM is low it stays there. All times though the RPMs seem reasonable nothing to low or too fast by ear.
The digital voltage meter turns on but I only get a basic menu screen and some basic info which I assume is again because I am not getting voltage from the generator. The J1 rocker switch when held up will close then open the relay on/off every second or two until I force it back off. It will not stay connected, again I assume because of the lack of voltage on one or more poles?
The 24V alternator is not charging and having done some digging I think it may have taken a hit and killed the regulator as the diode wire was burned off at the alternator. I replaced it with a good wire/diode but no luck getting it excited yet. This I am not to worried about yet as the worst case of a new alternator complete is only $80.
The HVAC unit makes some noise and tries to do things but the noises are timed with the clicking on and off of the J1 contractor so only a second then off again. I dont want to play much more with this yet until I get the voltage issue worked out.
Ever seen anything like this? Any tips? Thanks in advance!
