Starter Motor E93A

I guess I am my worst enemy here in that I am running 12V negative earth through a starter motor originally designed for 6V positive earth. Perhaps not surprisingly I am experienceing loads of problems!  Anyone got any suggestions on how I can use my nice new wiring loom designed for negative earth and an appropriate starter motor. Has anyone got a spare Starter motor anyway within reasonable travelling distance of Maidenhead.

  1. Starter motors of that era don't care if you use positive or negative
    earth. What problems are you having?

  2. When the motor is on the bench it turns quite slowly, when in the car it just clicks. In both cases the large battery terminal on top of the motor becomes very hot indeed - too hot to touch. Motor has worked in the past and I have had the unit overhauled several weeks ago as the brushes had lost their insulation - welcome any suggestions.

  3. Hi Tony,
     
    I see your message and I do in fact have a spare
    E93 starter motor. Condition unknown. I'm in Cornwall.
     
    Cheers,
     
    Roger.

  4. That sounds like either a poor connection on the terminal or a shorted
    winding. If your lights dim a lot when you try to start the car it is
    more likely a shorted winding.

  6. Hi Tony,
     
    I'm in Wadebridge about seven miles off your direct
    route should you be interested. I don't know the condition of it but it span
    quite readily the last time I tried it, about 10 years ago. As for price, make
    me an offer.
     
    Cheers,
     
    Roger.
