not everyday im asking a question!
 

I havent taken my E30 out for a few weeks now between driving my E34 and a E36, i got in it today, and the RPM gauge is flickery.

take a look at this

I would usually diagnose this as a CPS issue, but the engine does not stutter or anything, and i swear its not me with the clutch in giving her a squirt

any ideas?

also theres proof of my fantastic fuel economy in this car, backed up by calculated figures!

I never had this happen with the TACH but my speedo acted like that. The fix was to R&R the assemble and soldier the connections on the circuit boards.

Might be worth a try.

come on mang, you should know this one.

loose connection or the SI batteries.

Mine did that to until the accident:dunno: now its fine?

Gotta go with solder joints and SI batteries. Don't think having a crash on the chance it might fix it is worth the risk LOL

Hahahaha I want suggesting he crash his e30 I'd also say solder joints or batteries

i could be wrong, but it shouldn't be the SI batteries, the RPM gauge has nothing to do with the rest of the gauge and is a self contrainted unit. Non the less ill take it out when i get a chance and have a look. Im tracking my E34 this weekend so wont have time this one.

You just finished the v12 swap..

sure did! have some interior electrics still to go like the stereo and interior lighting, also my wipers and right turn signal have decided to no longer work, but other than that its done!

So why are you selling it after all this?

So i dont know why, and i cant see the logic, but i still hadn't got round to taking a look at the cluster. But i did leave my lights on a few nights back and the battery went flat on the car, but now after charging the car and driving around like normal again, its gone back to working 100% normally! how strange right!

Who said im selling it???????? I certainly aren't to my knowledge

Recharged the SI batteries?

ill update this, after that event, still working 100% fine a few months later! very peculiar!
