[Healeys] Electrical question

[Alan Seigrist]

Tom -

You're lucky.  You avoided releasing smoke like I did.

This wire, like the ignition wire, carries alot of current... it probably
corroded or melted a little bit in the harness somewhere and grounded out.

This is why it's a good idea, instead, to use this wire to power a relay
with a direct power connection to the fusebox.

Best Regards,

Alan
