Let me tell you about the times I have had electrical fires in my 1964 Marauders.
The first time it required replacing the wiring harness. That prompted an investigation into the cause of the fire and this video will tell you what was learned and my solution.The cause of the fire was a failed alternator. The solution is to insert a fusible link in the alternator wire.
An alternative solution is to upgrade to a 1965 or newer alternator. This requires the modification of the wiring harness, thereby detracting from the authenticity of your Mercury.
Hopefully, this information will help you continue to enjoy your Mercury.
