'88 Jag XJ6 3.6L

My cluster had been replaced by the P.O. some time in the past, and I'm guessing its not hooked up quite right.

1) oil pressure digital readout sometimes randomly reads 0. Usually it reads 0 for about 10 minutes and then continues to function.

2) ABS, low brake pressure, low brake pad, and bulb failure lights all blind me while I drive. Brakes and A.B.S. all seem to function, pads were supposedly changed a few weeks before I bought it- I think the rears may be down though. Been taking my time picking up the front-right bumper corner from the girl I bought the car from, so maybe that's where the bulb failure deal is coming from.

3) speedometer is about 10mph faster than your true speed.

4) is there any way to calibrate the mileage on the new cluster? The car has about 180k miles, and the cluster reads like 260k. Not really a big deal, but just wondering

Thinking of just removing the warning lights unless its a simple fix, since the car is actually mechanically sound.

Thanks in advance!

 

Lot's going on there, hard to zero in on just one thing.
The cluster is easy to pull out, why don't you give it a try and check out all the connections in the back, could be just loose.

 

I think I'll do that if I don't end up going to the Philly auto show tomorrow. Thanks mate.

 

88 Xj40's had 15" wheels. You're running 16's, right? Your speedo WILL be off.

 

Yes this is true, however it was off before the new wheel and tire setup. It's not a huge deal to me. My last project didn't even have a functioning speedo lol.
