I do have the TM's, I have read them -12 & -24 (I am still at a loss as to why there is a day tank at all on this genset).
( Gen sets larger than 3 KW have a day tank. Or a fuel system that funtions like one. Its simple. If the gen set senses that the tank is almost empty, the set shuts down for low fuel. Reason, so you do not have to go through the circle jerk of bleeding the fuel system. Some gen set do not do this easily. I spoke with Cat mechanic shop and they say, bypass the day tank and pump straight to the engine if possible since any excess will bypass internal check and return to the tank.
(Before I did this, I would troubleshoot the problem. Find out what is wrong and fix it. Hooking up stuff to bypass the system seems to me to be counter productive. ) Does anyone know why the military thought a 5 min run time tank on this unit was actually needed?
(See above answer. And yes I do. It would not matter if its five min. or 5 hours. Low, is low. As long as you keep the fuel system supplied with fuel, its a non problem.)
I have pulled the float out of day tank, checked it over visually, it looks good, I do not know how to verify function though aside from sliding the floats up and down in 'call for fuel' position and it changed nothing.
(In the TM is a test procedure. )
The low oil pressure dummy light is the only one that stays on;
( all the time?) all light up when you hit the test switch as expected.
Genset was running when it quit
(why did it quit?) 11 years ago, then sat in a barn till now.
No voltage at pump wires, already checked. Is there a terminal block that these pump wires run to aside from the CR27/28 TB?
What else do you need to know? I felt like starting a new thread was not useful since this thread is exactly what I am experiencing however I will do whatever is needed.
(You have no idea if its the same problem. All the comments before you jumped in, mean nothing, and confuse those who want to help.)
Thank you
First, see if the pumps work. Remove J5 plug. Take a wire and run it from 24 VDC+. to first pin D and then pin F. Do both pumps run?
