During "rebuild", was only the IP and injectors worked on? We're any other parts removed, or wiring removed? Because if someone works on something, and it runs before, and not after, whatever got "worked on" is suspect.
There should have been no reason to remove any wires, to pull the IP and injectors, but if so, I would start there. Could someone have miswired the dead crank switch?
The first thing I will do is correct myself. No dead crank on this set.
Hi Folks. I have an MEP004 with a white 4 cylinder diesel rewired single phase for backup power on my shop. I had someone else tear it down to rebuild the pump/injectors, as it was filling the crankcase with fuel and shutting down (although it runs great). Anyway the rebuilt parts are correctly back on,
(who put them back on?) but now the issue is when I connect the batteries the engine immediately starts cranking (no matter what position the on/run/start switch is in). I disconnected the hot wire at the solenoid,
(what solenoid?) but cant figure out that issue. Should I suspect a bad switch? (
No, or I would not. I have seen maybe, two start switches in the 28 years of working on the 004A and 005A) It also wont start on diesel alone now (fires immediately on ether),
(this could mean you are not getting 24 volts to the L1, engine fuel shut off solenoid) although it started and ran for about 1 minute initially. I couldn't get the engine to shut off with the switch,
(S2, engine start, run and stop switch?) so I pulled the fuel line to shut it down
(causing air to be allowed into the fuel line/IP) (shutoff
(what means shutoff?) didn't seem to do anything either, but I guess that's normal?). The fuel pumps work normally with either the battle station switch or with the main switch in the "start" position (doesn't run on the other 2)
(should also hear the fuel pumps run in the AUX position, with Battle Short switch on). I have 24 volts at the injection pump electrical terminals in the "start" position, but not "run"
(no voltage in the run position, no fuel, wont start) or "off"
(this is correct). I DO have the TM-9-6115 manual,
(Do you have the -12 and the -34 TM's?) but am a bit unsure of how to proceed. Any help would be greatly appreciated.....
Now, if you re-hook the hot wire to the solenoid, (what solenoid? Start solenoid?) with the batteries unhooked, and place the CB1, (DC Control) in the pulled out position, can you hook up the battery cables? If so, the problem most likely is in he control panel.
