    I have a Meyer E-47 that would make a better boat anchor than plow pump, but...

    We replaced the motor on this unit after the original bench tested DOA. The original slowed and eventually stopped working. The new motor worked great for about 30 minutes when it too, slowed and then stopped working. It was very hot to the touch, When we installed the new motor we cleaned all of the terminals and coated them with di-electric grease. The battery is new, also. (Both of them, F-250 Diesel). Parts store will replace the motor, but is there another problem I should be looking at?

    Just kidding, this thing would make a lousy boat anchor, too.

    I'd think maybe you just got a bad motor, but maybe the pump is seizing up and overloading the motor. But you did say it worked great up until the motor quit. I assume it's been flushed and new fluid added recently.

    Yes. took out the "blue milk" and flushed the pump. Cleaned the screens. Topped it off and added a little bit of dry gas.

    More than likely a ground issue.

    Problem with meyer motors is the the ground has to travel down the motor and through the aluminum housing. Not the best route since when you put steel and aluminum next to each other you get corrosion.

    I had one of these perform the same way, I sent it down to Smith Bros, Chuck found a bad crossover valve and a few other issues, I had him rebuild it, and no issues to date.

    In my opinion id be leaning toward the grounding issues.

    04SD nailed it. I pulled the motor this morning ( it is 8' F and snowing, so why not?). When this motor was refurbed one of the wires for the brushes had been pinched between the cap and housing. It ran until it finally burnt off.

    Crash935 I heeded your advice and cleaned the seat on the housing really well and put a thin coating of di-electric grease on there before I re-assembled to prevent corrosion.

    I have spent a lot of time browsing this site in the last few days and have picked up a lot of great tips. I definitely will be promoting the site to my friends. Thanks again.
