turn signals/hazard lights inoperative
The 97 TJ I just bought has no working turn signal/hazard lights...I got the Haynes manual but I'm a little at a loss for reading the schematics. I can do basic electronic testing but I can't seem to find the problem.

I've checked all the usual things...all bulbs are working...I replaced the turn/hazard relay...

The only thing I have found is..I think the former owner put in an alarm system at some no longer works.
I believe there maybe a grounding problem with the turn/hazard system.

I'm not sure how to tell for certain...or how to check...

I removed the cover from the turn/hazard relay...and using 12v. test light was check for power to the relay...inside the relay case on the PC board are 5 solder joints..when I touched the light on two different solder joints the light lite up and the relay began to flash and the turn signals and hazard lights worked properly...however...when I turn off the turn signals and the hazard button ....the relay continued to click....
So, I thinking something is not grounded properly ...but have no idea where to go from here...any help would be greatly appreciated...

Thanks Bill....

PS...i was connecting the 12v. test light from a ground on the body to the relay...when everything started working properly..other than the relay constantly engaging..

The test light was providing a ground through the light bulb to that relay that then got everything working, that relay is obviously missing a switched ground from somewhere. I'd follow the connection on that relay through the schematic and see if you can figure out where it is supposed to get its missing switched ground from.

Check where the rear tailights are grounded to the tub. On the Jeep that I got the previous owner installed tail light guards and made the area where the lights/guards meet the tub get corroded, and thus giving me a bad ground, causing the same type of problems. Just an idea...

If there is any equipment remaining from the no longer functioning alarm, I would get rid of that first. It may be a dead end for your current if it doesn't work anymore.
