Please help...electrical issue

Thanks in advance for everyone's help. I have a 2001 Jeep Wrangler. I took it to work one day and went to leave... it would not start.... my brother thought it was the ignition switch so he ordered one and replaced it...He replaced the ignition lock cylinder... still no start.... then we replaced the nutral safty switch... he has checked all fuses... replaced the ignition relay... battery is good... and the starter was checked and is good... what else could it be? gauges act screwy and radio does not work.

Have you tried to give it a jump start? Are the battery cables in good condition? I am leaning towards the battery or connections...... What does it do? Will it crank? weak crank? What exactly happens when ya turn the switch.

if it doesn't try to crank, and the battery and starter are both good, then it's got to be the connections to the battery. mine didn't start once because the ground wire for the starter had broken.

How do you know the battery is good? Did autozone or someplace 'test' it for you? If so it is very possibly still bad. I don't think they ever successfully tested a known bad battery I had when I went in for a proper replacement. They always test em and they always say it's fine... If it has not been replaced in a few years; REPLACE IT. Then you KNOW it's good for sure and can move on to other items. It would be overdue for replacement anyhow.

The next most likely is simply the cables. Check all of them or even just replace the main runs (alt, bat, ground, starter). And what about the starter solenoid... Can you measure 12V when it is trying to crank? Is it getting the signal? If so, the solenoid is still bad. (or your engine is completely seized).

There really isn't much to fail in this area... Start with simple and common (and cheap) and work up from there... Or take it into a specialist to do it all for ya...

Thanks for everyone's reply

The Battery is good... I not only had it checked but have tried a new battery just to make sure... It had brand new battery cables intalled. The starter spins when you jump the termanls directly to the starter. The engine is not seized it will jump when you give the starter power. It clicks once when you turn the key.

You jump the terminals on the starter which short it out, bypassing the starter solenoid. And it works. But the key doesn't. As long as the solenoid input is showing 12V, then the solenoid (or starter relay, I think it's actually just a relay on the 01... but I'm not near my FSM...) simply isn't triggering. Thankfully though that's a cheap fix...(likely <$20)

That's what it sounds like to me anyhow. It might even be as simple as the fuse feeding the relay.

Yep the order of things is the ignition switch which powers the starter relay (inside the Power Distribution Center on the passenger-side fenderwell in the engine compartment), which powers the starter solenoid which provides power to the starter motor itself.

The ignition switch, starter relay, and starter solenoid are all nothing more than simple electrical on-off switches, each one getting bigger to handle more amperes as they get closer to the starter motor.
