Mag Pickup repairs on my MEP804 a

[a3944296]

Any advice for my mag pickup repair. It tests dead. Zero Ohms unit won’t start. No fuel to injectors. Was running for about 1200 hrs. Can’t find a replacement.

Post your needs in the Parts Wanted forum.

I'm sure you already looked in the TMs for the NSN and civilian part number.

I have been, was going to try a generic pickup with the correct thread size. I’ll do a dead crank test for correct ac voltage first.

Search MSP6729 3/8”x24 around $20.
Another S.S. member purchased it for their 804.

Thanks

Got it ordered, thanks again. This forum has taught me so much. I also own a MEP 802a that needed help. And got it going thanks to the knowledge of others

Good Day: The TM says install till it bottoms on the toothed flywheel with the tip usually between 2 teeth and back out till you get 2VAC. Uh, we found if you bottom out turn it back about 4 turns, then using dead crank as you screw it in slowly obtain your AC and snug the locknut and don't Baby Huey it. Now connect after rechecking and you are about good to go. These guys also pick up metal shavings over time from starter and flywheel and eventually fail from that and garbage in the bellhousing. There is no repair we could figure out. The one on my Crossfire also just suddenly stopped working in the middle of traffic so they do fail for no reasons with time. Wish you luck.

Can I read the voltage from the pigtail on the pickup without using 2 people and read from A5?

Use alligator clips on your multi meter and face it towards the dead crank switch. Watch the multi meter as cranking. Also follow the TM procedure to the letter for setting. I thought I would save time and turned the MPU in 1/4, 1/2 turn at one point of adjusting and then heard the tip getting ground off. Lesson learned. Get the voltage in range and stop.
