It was reading 24.7V at the test points and batteries. After turning off, the voltage at the batteries rose to 24.9V. The battery charging stator measured in at 0.3 ohm. Spec says it should be 0.07 to 0.12 ohm.

I figure I'll bring this one back to life. I noticed on my MEP-701a that the batteries weren't charging. The bolt head on TP5 had been sheared and the B+ line was just not secured. Even after securing the line, the batteries weren't charging. I checked the AC lines going into the regulator...

I powered it up over lunch today, and it started up fine. No leaks. It ran a little rough while warming up but smoothed out. I adjusted the throttle and measured ~112V @ 60Hz through the convenience ports. I haven't put a load on it. Man it is loud with the ASK panels off. I hope the ASK...

I went to the local speedshop today and found some parker 836 push loc hose in their assorted hose bin. Cut the old hose off, pushed the new hose on, reinstalled and no more leaks. I reprimed the system but didn't get a chance to start it because the kids are sleeping. Hopefully tomorrow it...

Thanks to ETN550s trick of using a hand vacuum to fill the fuel filter, I was able to get the system primed. However, once pressure built in the fuel filter the feed hose to the injection pump started spraying diesel. It looks like the hose cracked right at the bend from the fuel filter under...

Sounds good. I truly appreciate the feedback. I didnt' realize the concern was dirty fuel getting to the pump, but that makes sense. I'll put the pump back together and try the vacuum method.

Thanks for the response ETN550. Isn't pulling a vacuum from the bleed screw to fill the filter housing similar to just pouring fuel into the housing which the manual warns against for fear of damaging the injection pump? Can you tell me where the check valve is on this system?

Here is a picture of the hole (circled in red) that is letting air get back into the feed instead of forcing it out the return line. Anyone have any ideas? Thanks.

I recently bought a MEP-701A with the ONAN diesel engine. I have been trying to prime it but it doesn't want to. It didn't feel like there was any resistance on the prime lever, so I removed the fuel pump. That is when I discovered the transfer rod was all the way in the up position. So I...
