Can’t even get a puff of white. ive gotta wonder if the MPU I ordered didn’t meet spec. The TM says I should be getting 800-900ohm. I only get 323ohm. I ordered the MPU noted throughout SS for this unit. when this unit was reset, it left at 2.6 hours; which is pretty close to when I bought...

New MPU arrived today. (MSP6729) Fresh out of the box on the shop counter, the MPU tested at 323 ohm. Hmm... In the 804A at wire 147c & 148c(both disconnected), it tested the same. Hmm... It also tested at 3.1vac when dead cranking. Ok. Only .1 over spec. Anyone think I got a bad or...

Thinking this one is too far gone.

Im getting voltage of 2.5v ac when dead cranking. The manual says it requires 2-3v ac. Im not getting the required OHM of 800-900 per the manual. Im only getting 701ohm.

Tested the MPU per the manual. when dead cranking, manual says look for 800-900 OHM at wire 147 & 148 I got 701ohm When dead cranking, manual says look for 2--3v at the same spot. I got 2.5v With mine being ground off a little, I'm going to put in a new one, its $20 and Ill know it should...

Roger. Heading back out into the cold to test the current MPU. If no go, will hit epay later on for the MPU and K2; I'm not in a hurry. Thank you to all who offered advice!

This is a 2.6 hour reset done in 2012. All of the pics I find show more of a button end on the pickup. Where’s the best place to source an MPU and a K2?

Thanks all for the info. 18 degrees in VA this morning but I took out the MPU because I’m ready to get this solved. Photos are below. I think mine may have been misadjusted and the flywheel ground it off. I think it should more of a button on the end. thoughts?

Hi guys, Thank you for all your replies. After a holiday break: Issue 1 solved. Non-cranking issue solved just by chance. The Cranking relay(k2) was the culprit. When my son was turning the S1 to the start position and I was checking wire connections, I accidentally bumped the k2 and the...

Copy Coug and 155. Thanks. I'll have to get it consistently cranking before I can go on the the non-starting issue. I'll give it another shot this afternoon, then test the MPU using the dead crank, and get back.

Thanks for the advice, much appreciated sir. I'm going to check the MPU whenever it stops raining here in Northern VA. Something is preventing the starter from consistently engaging and I'll eventually find it.

Hello everyone, newbie here. Thanks up front for all of the manuals and information I have already read. Great site and has helped me immensely! So I'm on my second MEP-804A. Very nice units. Like most, I bought this unit at a GOV sale that stated it was "cranking" but not starting. The...
