Electrical / Re: 78 Formula Tachometer
« Last post by Aus78Formula on April 29, 2016, 12:41:20 AM »
Hard to say, except that it's nothing to do with the gauge lighting which is a separate harness.

The tacho harness is a simple 2-terminal plug on the gauge, a single white wire that goes through the firewall to the HEI/dizzy but can be orange at the plug, while the other terminal goes to the fuses and is pink. It can also have a pink extension harness jumper onto it for accessories. This goes to the heater/AC option 25A fuse. Check that also.

You can check the wiring that goes directly to the HEI, unplug it and clean connection maybe, and try again. But most the time it's just that the tacho circuit board has died. You can get repro tach harness cheap too, should you want to try a few things first and fuses look ok. Can also run test wires direct from dizzy and a live feed to gauge too, bypass the wiring harnesses.

Electrical / 78 Formula Tachometer
« Last post by sv9119 on April 29, 2016, 12:17:36 AM »
Hello everyone, i have a CA 78 Formula with an olds 403. The tachometer has stopped reading my RPM's despite the fact that it lights up when i light up the dashboard. Would any of you happen to know if its an electrical problem as in a lack of power getting to the tach or something else?

Electrical / Dashboard lights...
« Last post by AKTransAm on April 28, 2016, 10:09:24 PM »
So I just got my 1977 Trans Am off the barge-loving it  ;D.  But it's definitely got some quirks.  Is there a trick to getting the dashboard lights on?  My headlights, taillights, and turn signals work just fine with pulling out the lights switch.  I figured the dash brightness could be adjusted by turning the light switch clockwise, but that doesn't seem to do anything.  Is this a common issue that can be dealt with?  Thanks in advance for any replies!

DriveTrain / Engine temp
« Last post by Bruni on April 28, 2016, 02:57:25 PM »
I recently had my car in a shop getting a "tune up" and since then, I've noticed the engine temp doesn't go past 160-170 degrees, even after an hour of driving.  Before the tune up, I know it had a 180* thermostat because I blew a heater hose and disassembled the engine and had heads ported and put on headers and a dual exhaust.  When I bought the car and prior to the tune up the temp would reach 220 all day.  I know overheating is bad, but 220 is normal operating temp, so my concern is this: 
Am I damaging the internals by running NO hotter than 160 all the time?  I'm wondering if the shop forgot to even install a thermostat.
I also had an issue of hard start after driving 30 minutes and letting it sit for an hour.  Seemed like there was no fuel reaching carb.  I do have heat shield tape on fuel lines by the carb all the way under the engine bay.

He's long gone the moment he posted. Are you after the bezel for radio or 8 track or both or...?

Restoration / Restored window guides
« Last post by Aus78Formula on April 28, 2016, 04:14:16 AM »
Nothing too fancy, but can restore the original window guides for less than the reproduction pieces and still be likely much better quality than them and also the cheap, thin adhesive felt sold to repair worn out originals.

I originally had mine redone years ago with very thick new felt that wouldn't scratch but it was too thick and left no adjustment room. So I sourced an extra 2 guides to support the glass while I restored the full set. I pulled the renewed thick felt off them, and had the metal blasted lightly. I then sent them and the bolts off for replating. I then tried a few different felts, including the repro set. Junk. I then sourced a fairly cheap but far superior felt that happened to come from Germany and arrived within a week! Fantastic quality and even the adhesive backing was night and day difference.

A few quick pics, the other bolts were already in used supporting the door glass when I decided to take a pic.

thanks for the advice  :)  I will be disassembling my new pump when I get it today, checking for burrs and stuff and making sure I pre lube it properly before I put it in. I think my dumb a** forgot to do that in the beginning and screwed my pump.

Hi, I am looking for the same thing. The AM/FM 8 Track with the bezel that surrounds the radio. Did you have any luck finding one?  Do you know of any others that might be out there?

I just bought a 1979 10th Anniversary Trans Am. I am looking to buy an original Delco AM/FM 8 Track and the bezel that came with the vehicle. If anyone is parting out their own vehicle or knows of the whereabouts of this type of radio, I'd appreciate being contacted.  Thanks. Mark
