    Diesel Fuel Injector question

    I have an early 70's Detroit 453N engine with a bad head. I have a good head on an identical engine but it has N45 fuel injectors where as the old original head has N50 fuel injectors. Can I just use the new head with the N45's or should I put the N50's from the old head in the replacement head...

    Mep 005A Charge dropping out?

    Yes, with Guyfang's help I did. It ended up being a shorted out diode.

    Well, just an update. It turned out to be a bad diode. Put a new set of diodes in, tested the old ones and sure enough one was bad. Its back to producing power just fine now. Guyfang I want to thank you for helping me with this. I would never have figured this out without your help. Thanks again.

    Mep005 Not Producing

    Well I couldn't find a 24 volt dc transformer locally so I took my 18 volt cordless drill battery and fed that into the 110 volt receptacle and started the engine. Still nothing. So I guess that means I'm going into the end bell. Unless I find something obviously wrong there should I replace the...

    Ok, I will look at those things today. Funny you should mention the flashlight batteries. I was already going to ask you about an idea I had. If I took a 24volt dc transformer and fed the 24 volts into the 110 volt outlet and then started the unit would that lite off the gen? My thinking is if...

    Yes, I have 24 volts dc at F1 and F2. I followed the directions in TM 5-6115-465-34 page 5-75. When I hold the start switch up I notice the voltage meter will climb up to about the 24 volt range until I release the switch. Anyway, after following the instructions in TM 5-6115-465-34 page 5-75...

    Mep005 Not Producing

    Update. Well I went and bought another speed switch. This one is the exact same model right down to the same serial #, which I thought was odd. It's a used switch but looks almost new. I know that doesn't necessarily mean anything but its not only clean but still pretty shinny. Doesn't look like...

    Yes, the new switch has that number. I have attached a few more photos. The vendor has agreed to let me return the switch. So whether it is the wrong switch or defective I may as well do that and start looking for another switch.

    The old switch is a Sunchro-Start model Go-3Ma Part # SA-1644 and I think it is nsn 5930010219378 and I believe TM 5-6115-458-34 and TM-07536A-35, DoD drawing # 70-4058. I also found on the trouble shooting schematic on the generator... Speed Switch- S9-1 Start disconnect and field flash, S9-2...

    Mep005 Not Producing

    Well the latest is that I bought a new speed switch and installed it, but the generator is still not producing power. Not only that but with the new speed switch the engine will not shut off. I had to disconnect the plug to the speed switch to kill the engine. Shouldn't a new speed switch be...

    Mep005 Not Producing

    I just took the cannon plug off the speed switch and used my vom on the speed switch pins and determined that I had continuity across pins a&b and g&h but no continuity across pins a&c, d&e or f&j. I took the speed switch apart and the three switches in there do not appear at least to be...

    Mep005 Not Producing

    Ok, I did all that and have found out a few things. I jumped across pins A & C on the speed switch J37 plug and found I do have 24 volts across F1 & F2 coming out of the exciter box. According to the TM that indicates the problem is probably the speed switch. I did the continuity and...

    Ok, now your talking a language I understand. I know a thing or two about beer cans. I believe I found the beer can ah....I mean speed switch you are referring two. The breaker on top did not appear to be tripped. I pushed it down anyway and started the generator but still nothing. Could you...

    Mep005 Not Producing

    Ok, I checked for dc voltage at the 110 outlet like you said and there is none at all when holding up the start switch. I am not sure what the speed switch is? Is the schematic you are referring to on the generator or in a TM? Thanks for your help.

    Mep005 Not Producing

    My Mep005 generator has stopped producing power. Only has 80 hours on it. after it quit I did get it to pick up one more time by holding the start switch longer. But now it won't pick up and produce no matter how long I hold the start switch. Any idea what I need to do or replace?
