Shes finally on the road! with other problems....
Posted by: AKcorvair ()

After Finally getting the 3 speed Transmission on my 1964 corvair rebuilt. Im finally enjoying driving the car!


some problems i have encountered after driving it around town the past couple days.


1: My idiot lights have never worked since i bought the car. noticed one bulb was burnt and the other was missing. I replaced the bulbs and they now both work with the key in ignition on. the GEN/FAN light will dimly stay on and will get brighter as i accelerate, all the time, every time.


2: I have an oil pressure gauge hooked up with the corvair adapt a bolt on top of the oil filter. on startup idle. it reads about 30PSI. after warming the car up on a 20 minute drive or so the pressure will drop pretty low. sometimes even show 0-3 on the gauge. hoping to confirm with a different gauge soon. oil is amsoil z rod 10w-30 from clarks with clarks filter.

3: My longest drive with the car so far has been about 30 minutes of street driving and the car/weather was pretty hot and the TEMP/Pres gauge illuminated. i immediately pulled over and let the car sit for a couple minutes. and when restarted light was off. 5 minutes later down the road it came back on sad smiley but the car drove perfectly. idled smoothly and quietly.Also, oil pressure sender is new from clarks.


anybody swap out the head temp sender/switch completely to install a temp gauge sender? i care more to have a gauge than a very vague light come on

Congrats! I knew you get it done!

1 Gen. is not charging properly. Voltmeter on battery posts....rev engine to 2k rpm

Voltage should rise to 13.6 or higher..

2 No lifter clacking? No problem... Lifters clatter at 7 psi usually. You have thin oil...don't worry.

3 Temp switches decay the temp it switches on at with age and heat cycles... get a new one.

Thank you!!

Great reply! I will check out the voltage tomorrow while revving.

I was wishing mine would run half that.

So I just tested the bolts at the battery. Was 12.3x at idle. Revved it up and did not change.


Clearly my generator is not going its job.

Any recommendations? Repair? Find a rebuilt unit? Alternator conversion?

Would really love to keep costs low on this one.

Any other tests for the generator to see if it’s something simple like changing the brushes etc...


Thank you!

Could this be a generator that was not polarised?

I will try to polarize and motor it today. Is it better to obviously remove the belt before doing so?

Polarize FIRST....


If that doesn't fix it... then remove belt and try to motor the gen.

Tried to polarize and didn’t fix. Gen light still on very dimly at idle and gets brighter as rpm increases

Will take belt off and motor it.

So I just took the belt off and motor the gen and it spun very nicely and pretty fast.

I’m thinking now I look into replacing the voltage regulator?

Here’s an update of my crappy luck!


Got a new voltage regulator today. Installed it. Polarized it. Started the car and the gen light completely off!!!so excited I was doing cartwheels.

Drove about10 miles to my destination without any problems. Turned the car off and the gen light illuminated. With the car off!


I was like hmm, that’s weird let me check out the engine. I open it up and notice smoke coming from the generator itself... then all of a sudden.. much more
Smoke coming from the gen. THEN I see the ARM wire from the V/R start bubbling up and burning the insulation. I panicked and ripped the BAT wire going to the regulator and burned my hand. :’(


Did the store sell me the wrong regulator? What the hell happened. The car started and ran beautifully until I turned it off and the light came on and Things started melting

The cut in relay on the regulator stuck. Probably fried the generator.
I've had it happen but I managed to whack the regulator and unstick it before it melted my harness.

You can see in these photos where I ripped the wire out to stop the current. All the insulation came off the wire since it was boiling hot.
I got the regulator from auto parts store “made in USA” 30 amp voltage regulator

Do I bit the bullet and ordered a new generator and wire harness from Clark’s.


They do not have a voltage regulator in stock so I’m trying to source one elsewhere. I returned the auto parts store “standard” brand one


One thing I’m confused about which I noticed after the old reg I took out had “ neg ground” on the side and the auto parts store said “pos ground” on the side


Can somebody explain this to me and which one is correct for the corvair?

Thanks!

Negative ground for the Corvair.
Your picture shows negative or positive ground.
I've never seen that before.
