Bean Posted March 23, 2017 Report Share Posted March 23, 2017 Hi Marc, When a starter jams up it's considered a short to ground - meaning the positive wire is essentially going straight to ground which generates a huge amount of heat in the wires when you attempt to start it. Usually the circuit is fused and the fuse blows. In the case of the starter circuit - it's not fused so when you attempt to start it, something literally has to melt down until the connection is broken or the circuit is interupted. (Starter is engaged by the switch - so as soon as you release the key the circuit is interupted) Power at the starter is only triggered by the switch - but if there is something else causing a mechanical short to ground - something will have to melt down before the circult will be broken / interupted. You need to find someone locally who is an excellent auto electrician - or you need to learn DC circuits and trouble shoot it yourself. Asking questions without a full understanding of DC circuits is not going to be of any help to you. Rabin Quote Link to comment Share on other sites More sharing options...
