01-24-2012, 01:04 AM #1Okay, I would very much like to get the cruise control function to work again, and the extent of my knowledge of cruise control is that there is an amplifier involved haha, soo I guess my question is what can I do to get the CC back working again!? Also, the tachometer only works sporadically, so any help/suggestions there would be appreciated as well.
Thanks folks!!!

The tachometer has its own "amp". See here for a $50 one:

Usually comes down to replacing/repairing the amp. It develops hairline cracks in the solderjoints over time.

01-24-2012, 05:41 PM #4Awesome, if I could get the tach to work I would be extremely happy, and if I can manage to get the cruise control working there's no telling what I'll do haha. I'll have to look into ordering one of these tach relays

You problably will not find a dead resistor, if you want to repair the amp yourself than you have to do over all the tin solders-it takse about an hour to do this properly.

As you can see on diagram, K1/1 is OVR pelay and N8/1 is tach amp
http://img697.imageshack.us/img697/3941/p1030313.jpg
OVP relay comman problam is also bad tin solder or broken fuse on top of it.

If tach doesent work than there can be a problem with OVP relay, tach amp gets its power suply from OVP relay.

(01-30-2012, 03:38 PM)aaa The OVP relay is a 1985 and later thing.
I guess that means I dont have to worry about it!! I am also going to add an extra ground to the cluster soon because I suspect that may also be contributing to the problem

02-02-2012, 01:56 PM #16Is there any place in particular on the back of the cluster that would be especially good for connecting an extra ground? I think it may help with my slightly jumpy temp and fuel gauges so I would like to try it out

02-02-2012, 06:33 PM #17Okay so I just disassembled my odometer and re-set the mileage to about 270k from 226k, and hopefully scratching up the shaft and adding loctite to it prevents the little pot metal gear from slipping once I re-install. Im also gonna put in an extra ground when I reinstall the cluster as well, and then all I will need is for the new tach amp to come in the mail and I should have all functioning gauges! Or at least I can hope haha

Why would you do that? Should either have gone for 900k or like 30-40k
