My tracker started then one day it would not start changed the starter and all it does i clicks and if you keep trying the posative wire gets hot on my 93 geo tracker

Check for spark at the spark plugs. You may have a wiring problem. Check wiring for damage from rodents, connections that are corroded or loose.

Voltage drop test starting system , could be a bad cable . Starter Voltage Drop

You got the wires backwards

Make sure wires are tight and battery wires are tight look for wires sitting on manifold

Check the distributor

You have an intermittent problem in your start circuit. I'm sure you also have some choice phrases to describe it, go ahead and vent, we have all encountered frustrating problems.
The reason shops can't find it is because it isn't happening when they look at it. Anytime a hot engine is shut down a lot of heat is generated in the engine compartment. So opening the hood helps yours cool down faster and start quicker, a good clue. I believe if you had it at a shop when it won't start, they might find it. First thing they would check, or you could if you have a voltmeter or testlight, is if power is reaching the starter from the ignition switch in cranking position. This is the small wire on the starter solenoid. If there is power there when the engine won't crank, quickly reconnect the wire and verify if car will crank or not. If still nothing, it may be a poor ground wire(battery or engine ground) or a poor battery cable, since you know the starter is good. If you reconnect the wire and it suddenly starts working, it may have just been a loose connection on the wire you pulled off. If it keeps happening when your hot engine is shut off, test may have been invalid-intermittent problem has only now come back, so run the same test again.
If you or a tech ever find no power on the solenoid wire in START, that narrows it down to the path from the ignition switch to the starter solenoid. One needs to trace that path, looking for where the power is stopped. A couple of possibilities are the starter relay and the neutral safety switch. You could try a new inexpensive starter relay and see if that solves it. If not, then further testing needs to be done before giving up or throwing some expensive parts in and hoping. But you have narrowed it down which helps. It could be some arcane problem like a ground source for the starter relay, or who knows what. Have the start circuit checked, and it would be easier if the no crank condition is present when checked. Good luck.

my geo tracker wont turn over the lights wont come on nothing is working iv tested the battrey its fine and checked all the fueses they are fine too why is there no power to any thing?

new battery....or alternator.....try boosting it if it starts leave it running and remove cables... if it quits when u remove jumper cables then u need alternator or check its fuseable link ........if it stays running it was your battery and your starter was probably ok i...u didnt need to change it or both starter and battery were bad ....starters kill batteries when they are failing and start to draw too much amperage from battery ...another quick way to tell a battery is dead,,,,,,is to look and see if its swollen or bulging...tis the season for batteries and alternaters ;-) good luck

check that the small [exciter wire] is not loose or disconnected at the starter motor solenoide !
It could also be a bad starter relay!
try bridging the exciter terminal to the posative [big cable ] on the starter solenoide with a screwdriver or a piece of heavy guage wire to see if the starter activates!
if it works would it could be a faulty relay
Cheers Rob

changed the wires
