An IGNITION System has two Electical Circuits..
An Eletrical Switch is two POLE..a Negative Pole and Positve POLE..the Positive side is the FUSE-side..
A engine Starter MOTOR works by useing a STARTER SOLINOID/so as too NOT drain the 12v Battery..at the same time it will pass a High Voltage to the Distributor<<--might want to check me on that one..
If a REMOTE Starter Switch will start the Engine..then the Engine uses a RELAY on the FENDER(usually)mounted there..<<<---I forget how to TEST that Part..???..I think the REMOTE Starter SW> is the TEST..
Check the RELAY on the FENDER Well.
I have a 1997 jeep wrangler sport 4.0 liter auto, My question is today I went out to the jeep and turned the key to start it and nothing happened, all power is there and the funny part is the remote start does start it, checked the shifter to make sure it was in park, and i will be checking the fuses because i think the remote starter bypasses the ignition fuses. any ideas will be a great help, thanks.
