starter motor question.

Ok
I am working on the electrical system of a friends 1963 Mini. My first (mini not friend)
It was an old autocross car that had been quite molested in the electrical department as well as most other places. My friend wants to put it back into street trim I agreed to help him with fabricating a dash and doing a bead rolled aluminum rear panel and also install all the glass. Well I started looking at the electrical system and about puked it was a fire waiting to happen, bare splices, undersized wire no grommets , well you get the idea. so I decided to fix it up a bit well one thing led to another and after about two hundred hours of tracing, and repairing I am about done. While doing a few last checks I found that the starter motor will read a dead short to ground from the terminal that is fed from the starter solenoid. The car had been converted to an alternator and therefore Neg ground some time during its checkered past. I am looking for some idea of what could cause the short. I know nothing about positive ground conversions and doubt this is normal but I have been known to be wrong before.
Thanks
Ray Mc

I learned that the little car has a direct drive starter and remote solenoid so an ohm reading across the armature is normal. I put power to the starter motor and it spun I am repairing and replacing the Batt cables and connectors tomorrow and hope to run a check on the complete system with it powered by my Batt charger

very close to what my suggestions would have been - put power to the starter and if she spins back up from there
