CRUISER'S MOSTLY RENIX TIPS IMPROVING THE INSTRUMENT PANEL GROUND NOVEMBER 17, 2015 SALAD 27 COMMENTS The ground point for the complete instrument cluster on your XJ or MJ is located up under the driver’s side dash. If you lay on your back and look up under there with a flashlight, without wearing a hat, you will see a black wire attached to a shiny piece of metal almost directly above the hood release knob. The screw will have either a ¼” or 5/16″ head on it. This ground point is responsible for handling the ground circuit for the following items: Dome lamps, seat belt and key warnings, transmission power/comfort switch, wiper switch, headlamp switch and delay module, fog lamp switch, cargo lamp switch, all instrument panel grounds and illumination, power windows and door locks, cruise control dump valve, and a few more things. The problem is that where the ground point is located does not share good contact with the chassis where the ground should be. The solution is simple: Make up a jumper wire with #10 gauge wire about 10″ long. On one end, crimp on a ¼” round wire terminal. On the other end, crimp on a 3/8″ round wire terminal. Remove the screw from the existing ground wire and attach the small terminal of your jumper so that the original wire and your new jumper share the same attaching point, one over the other. Look above the driver’s side plastic kick panel just forward of the top of the hood release knob. You will see an 8mm stud there. Attach the large terminal end there with a washer and nut over it tightened securely. Use a coating of OxGard at all ground contact surfaces when attaching the screw and nut. **Special note for Comanche owners: Make your jumper wire 12″ long and attach it on the driver’s side kick panel close to the fusebox on the 8mm stud.**

I read somewhere about using one from the new Gladiator? -
Questions about the stock engine bay
cruiser54 replied to Salvagedcircuit's topic in MJ Tech: Modification and Repairs
No coil wire clip. Pretty sure that's normal regarding the dizzy connector. Junkyard only on the Power/Comfort switch. I would bypass it anyway. -

for future reference. CRUISER'S MOSTLY RENIX TIPS RENIX CPS TESTING AND ADJUSTING OCTOBER 30, 2015 SALAD 131 COMMENTS Renix CPSs have to put out a strong enough signal to the ECU so that it will provide spark. Most tests for the CPS suggest checking it for an ohms value. This is unreliable and can cause some wasted time and aggravation in your diagnosis of a no-start issue as the CPS will test good when in fact it is bad. The problem with the ohms test is you can have the correct amount of resistance through the CPS but it isn’t generating enough voltage to trigger the ECU to provide spark. Unplug the harness connector from the CPS. Using your voltmeter set on AC volts and probing both wires in the connector going to the CPS itself as shown in Figure 2 as Connector A, crank the engine over. It won’t start with the CPS disconnected. You should get a reading of .5 AC volts. If you are down in the .35 AC volts range or lower on your meter reading, you can have intermittent crank/no-start conditions from your Renix Jeep. Some NEW CPSs (from the big box parts stores) have registered only .2 AC volts while reading the proper resistance!! That’s a definite no-start condition. Best to buy your CPS from NAPA or the dealer. Sometimes on a manual transmission equipped Renix Jeep there is an accumulation of debris on the tip of the CPS. It’s worn off clutch material and since the CPS is a magnet, the metal sticks to the tip of the CPS causing a reduced voltage signal. You MAY get by with cleaning the tip of the CPS off. A little trick for increasing the output of your CPS is to drill out the upper mounting hole to 3/8″ from the stock 5/16″, or slot it so the CPS bracket rests on the bell housing when pushed down. Then, when mounting it, hold the CPS down as close to the flywheel as you can while tightening the bolts. Another little tip to save tons of aggravation is to stick a bit of electrical tape to your 11mm socket and then shove the bolt in after it. This reduces the chances of dropping that special bolt into the bell housing. Revised 8/8/2016

AC Expansion Valve Retrofit Question
cruiser54 replied to ktmall07's topic in MJ Tech: Modification and Repairs
You don't need to replace it when converting from R12 to R134a. I've always left the original valve in when I've converted. 38* vent temp in Arizona summer heat. -
FWIW, I only use the Mopar thermostats. I learned my lesson the hard way.

This^^. VERIFY.

Small Radiator issues?

I wouldn't do the condenser if it isn't leaking. -

Just remove the grille. Phillips screwdriver. -

AFTER it has been bled and you have a good pedal, do the 40 pumps. You may have gotten a faulty master cylinder, but they tend to leak into the cab. Is the rubber hose original?

Pump the pedal about 40 times and walk away. See what happens after 20 minutes.

88 MJ exhaust manifold swap to 91+?
cruiser54 replied to KA88MJ's topic in MJ Tech: Modification and Repairs
An alternative on exhaust manifolds: As far as exhaust, you can use the Renix exhaust manifold and be fine. If you want to use the HO exhaust manifold, you must go with an HO headpipe and screw your O2 sensor into that headpipe. Standard Renix harness is plenty long to do so. A bung can be welded into the HO manifold to accept the EGR tube.
