if your talking about the one on or in the starter, you have a bad solinoid. This could be or come to be very serious, very quickly, for instance, if it sticks while the gears are engaged it will burn out the starter and maybe a feed back that could burn wires. A starter uses a lot of juice and the wires could get very hot if the starter sticks
The starter relay is built on the starter.
The neutral safety switch keeps the starter from engaging when the transmission is in any gear EXCEPT park or neutral. A faulty switch would either allow the starter to engage any time or not allow the starter to engage at any time.
Battery Battery cables Neutral switch (if auto) Clutch safety switch (if std) Starter Starter solenoid switch Ignition switch do other functions work? (wipers, turn signals, radio, etc.)
there are several problems that could cause this on a jeep one is the ignition switch, the starter, the gear changer on the transmission.
your ignition switch or the starter solenoid is bad try jumping the solenoid instead of the starter, if this does not work, then change solenoid
Probably a bad key switch, the starter needs voltage from the switch to the solenoid to engage so start there. You might also want to look at the starter, sometimes something can get lodged down there and bridge the connection.
You might want to check your park-neutral safety switch, if it is not engaged the starter will not run.
i would check the cranking circuit,starter,starter relay,ignition switch,neutral safety switch.
It is a plunger type switch screwed into the top of the transmission casing.
The brake light switch is high up on the brake pedal. It has a plunger on it. The plunger releases when you step on the brake pedal and retracts when you release the pedal.
There is a brake light switch mounted high up on the brake pedal. The switch has a plunger which is released (extends) when you step on the brake pedal. This completes an electrical circuit. The switch has either come loose from where is it mounted so that the plunger is released all the time or part of the plunger has broken off. This has the same effect as having the plunger released.
Starter solenoid?
