MG Car Repair: relay starter, mg enthusiast, battery voltage

Question
I recently purchased a 1975 MG.  The relay starter went up in smoke after a short drive.  What would cause this?  PS: Where can I locate a wiring diagram?
Thanks,
Ron (MG enthusiast)

Answer
Hi Ron,
I have no way to tell what made your relay quit. A relay receives full battery voltage on the coil and on the contact points so no short can cause a relay to fail.
I put a wiring diagram up on my web site for you plus the index for the diagram.
