tach

Hello all My '88 RRC has been running pretty well since tinkering over the past few months, and much thanks to all here. Two issues I'm still encountering that confuse me are that both my Tach and Temp gauges are inoperative. The rest of the gauge cluster works fine. I thought these issues...

Just a heads up, I stumbled on a solution for a low tach reading I was experiencing for about the last 200 miles. I had a failure of the distributor rotor - no spark getting from the distributor coil to the plugs. I replaced the EuroSpare rotor with a Lucas replacement and the car started...

Gentlemen, Sounds odd, but when I depress my brake pedal the tachometer on this '95 RRC goes to zero. When I take my foot off the brake, the tachometer returns to the correct RPM. Starting the truck with foot off the brake, the tach is normal. Sounds as if the brake circuit is shorting the...

Hi there! So, I replaced my alternator recently and the tachometer stopped working. I'm wondering if it has to do with those little capacitor looking things on the back that plug into two connectors on the back, which I had to transfer from the old alternator to the new one. Any thoughts...

'93 LWB, my tach needle has been bouncing and intermittent for the past couple of years, and this week it died completely. The alternator is obviously charging, so where would I start looking to troubleshoot this? Do the tach units themselves fail or is it the signal it's getting?

Lost speedo, tach,fuel gauge, temp gauge, indicators & HEVAC As Title: Lost speedo, tach,fuel gauge, temp gauge, indicators & HEVAC HEVAC still works but have lost display. Out and about so have pulled all small fuses for a visual check under seat and in engine bay and look OK. P38 4.6 1996...

Hi my name is Frank (Belgium). Bought second hand rr p38 1997. Normaly a 4.0 but there is a 4.6 block in it from Turner Engineering (uk). After 8 months most of the known problems i did repair myself (fuse box, eas, etc). But now i have no tach anymore. I've read topic "erratic tach needle" and...

All of the guages in my 95 RRC LWB work fine except the tach. It bounces all over the place. sometimes it runs smooth then will start bouncing +/- 1k and even drop to 0 then bounce back up. The engine itself is running smooth, no surging etc. when this happens. I read where a bad alternator can...

I just finished replacing my Steering Angle Sensor (the method without removing the whole dash) and after getting everything back in place decided to crank it up. Of course, the lights are all still on because I have to get the sensor initialized at the shop. But now, the tachometer and temp...

Tach Guru's. Can you put a meter on brown and/or white wires to check? Tach hasn't been working sine I got the truck. On my last truck I had the same problem. Bought a new alternator from BP of U and tach worked right away. I just did the same thing with the current truck. Tach not working...

2003 Range Rover - Brake, DSC, non-functioning Tach and Temp Gauge I have read the forums and have not found anything close to what I am currently experiencing in my vehicle. I took it to the dealership and, of course, the car didn't do this while they had it and they said it was not showing...

so driving my p38 intermittant tach and speedo drop out. altinator and battery i just replaced with new. also traction control and gear box fault apear on instriment cluster?

Hi all! I'm new to this forum and recently purchased a 98' 4.6 HSE w/ 85k on the Odo! It came to me in great condition except that it did have a radio-well at least not a complete radio. There was a Kenwood deck w/o the faceplate that I decided to replace with a Sony unit. To my surprise, the...

I just wanted to post this up because maybe it would help someone else. My tach was not functional, occaissionally would move around at idle, but as soon as I would start driving it would stick around 1250 RPM and stay there indefinitely, even after shutting the engine down. Searched on this...

So I've noticed recently that while stomping on the gas pedal (to the floor), the tach will sometimes drop down to 0 and back and act all erratic. Also during this time, sometimes, the EAS truck/arrow light comes on, although there is no action on the christmas tree just steady solid light on...
