hit starter button—wuh wuh stop... hit starter button again—wuh wuh wuh... stop
Lots of current draw—the copper strap from the solenoid to the starter case gets smoking hot.
It's been leading up to this, but up til now it has been starting. Now, forget it. It won't spin enough to start.
That copper strip is getting very hot, though. Batteries are fully charged.
Seems like it's gotta be shorted starter windings, armature or field.
One thing that's got me wondering, though, is that I have a lot of Lucas in the crankcase, and it's very cold out—below freezing. Couldn't be the Lucas getting thick and gumming things to a dead stop, could it?
series 60 bad starter?

The Lucas isn’t helping. It will definitely make it harder to crank. Sounds like your battery connections could use cleaning or tightening up. For now, make sure terminals are tight. Hook up good jumper cables, if using a car, wait at least 20 minutes, start it up. If it cranks a little better, but not enough to start. Charge it up again, for another 20 minutes or more, and use a good shot of ether.

Hooked up jumper cables for an hour. The batteries are charged as high as they can be. All terminals are as tight as they can be.
It doesn't spin long enough for ether to do any good.
There is plenty of current going into the starter. The copper strap gets so hot it looks like it's gonna melt.Rideandrepair Thanks this. -
I'd make sure your cables aren't dropping a bunch of voltage, shorted, ect. Especially on the starter side - its easy enough to pull a battery box cover and clean it up, but nobody ever willingly wants to reach down in the frame rail. Check the cables aren't rubbed anywhere as well. To change the starter you have to unhook them anyway, might as well check it with your meter while it's off, right?
Try barring engine over by hand. If its a total bear to bar over, then its that much harder on your starter. Remember, more mechanical resistance = more amps.
