Not fusing your starter would make as much sense as deciding not to have a circuit breaker for one of your big appliances
, like a dryer at home because it was just too much current
. The regulations
are old, but there is a push to add an inline fuse in the starter circuit regulations
. If you have ever seen what happens when a starter solenoid locks up, it isn't pretty, and the starter continues to heat up along with the battery cables
and batteries until the weakest link melts, and sometimes across something that will burn. Go ahead and put a good size fuse in line. It's best to contact the engine manufacture and find out what the correct fuse would be. Buy the fuse with the most surface area to bolt to so there isn't much resistance at the connections. You can buy circuit breakers, but they are expensive. Mount the fuse with a cover so there is no chance of hitting it with a wrench to ground.
