There is an under dash relayed block....that has 3 different relays on it. My relays and thermal fuse were fine....but one of the ends of the relays was severely corroded. I was very dissapointed to find that they weren't even soldered on in the first place. More of a "crimp" on style. Well...it's soldered now and the controls work perfectly! Thanks...and hope this helps someone else out there. - -Mike __________________________________ Do you Yahoo!? New Yahoo!

I'll do some research on dielectric grease for connectors... one of the things they do (or did in the '60's ;) in cable/wiring is to use lead blocks to interconnect aluminum and copper wires. lead doesn't corrode and permits the coupling together of dissimilar wires... solder is mostly lead... this same problem can happen on the back of our instrument clusters, soldering really isn't an option. But taking and cleaning the connections for gauges with an eraser or contact cleaner is. Be careful not to us too abrasive of an eraser... the white "magic rub" kind work nicely. The corrosion built up on connectors can lead to automotive fires. The use of amp gauges in the older jeeps that used them also have the issue of all that current passing through aging wiring... a formula for disaster... volt gauges make more sense... It's a good idea to check ground connections as well... later, john Mike Redding wrote: Got the heater figured out Saturday. There is an under dash relayed block....that has 3 different relays on it.

Off the cuff, I was thinking 87 to 89 would involve the least hair pulling, is that right? wrecked it Sunday night in a snow storm, sure that the insurance will total it. lots of damage to rear hatch both tail lights (guard rail -at- 60 MPH) drove it into town after collecting my cargo, seemed to run fine and handle well despite it all. ------------------------------ Date: Tue, 23 Dec 2003 00:09:58 -0800 From: john meister Subject: Re: xj: What Years actually you could put that in any year from '87 and up... you'd only have to change the intake manifold and a few other things to use it in an HO setup... of course if you change the computer/wiring... I'm not sure if the HO engine internals are that much different... might need to do a little research on that... but other then the fuel delivery the motors are pretty similar... john Jason wrote: > I have an 87 XJ 4L 5 spd (only 106,000 miles), what other years would the > power train fit in? > > Off the cuff, I was thinking 87 to 89 would involve the least hair pulling, is > that right? > > wrecked it Sunday night in a snow storm, sure that the insurance will total > it. lots of damage to rear hatch both tail lights (guard rail -at- 60 MPH) drove > it into town after collecting my cargo, seemed to run fine and handle well > despite it all. > - -- ---- - ------------------------------------------------------------------------- ** john-at-wagoneers.com ** Snohomish, Washington USA - where Jeeps don't rust, they mold. ** trust Jesus ** - ------------------------------------------------------------------------- The revolt is underway, the penguin is coming...

Overall a very good solid truck. Runs, drives - current tabs - clear WA title. A few minor issues, leaks, exhaust probs - It does need some TLC but will be a great rig. One too many vehicle - need to sell one ASAP! Offers/Trades Considered. Will trade for a Jeep Wrangler - I can email pictures. In Seattle area. Thanks! === ------------------------------ End of xj-digest V1 #1753 *************************
