Thanks and Cheers

A combination of things probably caused this to happen. After being stored for the winter, the amount of resistance in your wiring will be at an increased level and possibly enough heat would be generated to cause fusible link meltdown. That's a good thing, because it prevented further damage to wiring and other components. Just the increased amount of corrosion on the starter motors rotor & stator after sitting all winter will cause it to turn over slower or cause a higher amperage draw, creating a lot of heat. You possibly ran the starter motor a little longer than what it takes to start the engine also. Try cleaning all your electrical connections first before looking for other problems that might not exist. That's my guess.

Also depending on how damp it was where you stored it, you may have picked up a bit of corrosion in the grounds or other connections. Overheating circuits are often due to corrosion and resistance in their connections.

A side comment, you don't need to post the same question to two different forums. The front page shows all the latest threads regardless of which forum you post it to. Extra copies of the same thread starting question tend to make searches difficult (which one is the one that got answered?) and also makes it difficult to detect which one had the right answer for a reply.

FWIW
