 Topic: Wd45, a good enough ground?
Posted: 14 Feb 2012 at 12:30pm |
Last month my boy rebuilt the engine in this WD45. The starter would bearly turn it, had the starter fixed, still no good. He took it back and they put in a high tourk windeing and specal ground, still no good. Took it back and they put in another winding and now it spins over on 6 volt like it was on 12 volts.
Wd45 on trailor, he took it to a neighbors and hooked up a feed grinder and ran a back of feed. Every thing is good now.

If an engine is rebuilt good and tight it will sometimes have to be pull started the first couple of times until it wears in. This is fairly common with old cars too

That is the orignel WD45 starter. They put a stud and lock nuts in place of one of the field screws.
It wouls start OK with a 12 volt boost, he wanted to crank good on 6 volt.

JC, have your battery load tested. If you're still running 6 volts, remove any ballast resistors that might have been put on. The 6v coil should measure 1.5 ohms on the primary side. When you release the starter and it fires, that usually says low cranking voltage.

Check the starter bearings for wear. If the armature drags on he pole pieces it won't crank good.
