Hello all!
I just noticed a new light turned on in my 74 2.0 dashboard, since I don't think a user manual has been in the car since 1980, I need to ask you guys what the lamp is all about.

I reviewed oil levels, temperatures, and nothing, it was low on oil in the transaxle, but I toped with some 700ml of oil, but the light is still on, motor oil was also a bit low so I added 0.5L, but the light is still very on, brakes are also fine.

I was thinking maybe electric issue, but I rather ask here.

All else should be fine.
Please your advise. I am still learning my car.

The light is not in full brightness, (the picture is a bit brighter than the actual lamp is)

If you are referring to the red “g” light. Generator=battery, electric issues

If you have a voltmeter / multimeter, please check your battery voltage with the car running. Post your results here.

And that is why I was afraid to ask… thanks so much!!!

It will have to get some love then.

13.4 V is what you want to see.

Thank you so much!

I will get a voltmeter…

Actually, (G)enerator = Alternator

Something in your charging circuit is not working properly.

Yes, you are correct.

Is the belt still on? How is the tension?

Posted by: bkrantz Aug 27 2023, 10:01 PM

^^^ Yup, start by checking the fan/alternator belt.

I got back from my Sunday tour, and store the car, I will look for the belt tension tomorrow and get a tester I think I will get one tomorrow.

Thanks to all..

I overcome my fears and got back to the car today.

Started to see with fear, and got my hand into the belt.

It is looooooose!, so I got a rush of confidence, hehehehe, it’s just all loose, so just needs a little more TLC, jack and stand, and some time, I promise I will try to fix it on the weekend.

It had me sweating thinking on buying a new generator, connecting cables etc, etc…

Last year my generator failed and it was fixed by an electric with a very questionable background for $200us
I was thinking the lamp was something to do with that fix, it apparently was, but not as bad as I was thinking.

A loose fan belt it like a loose pants belt. Things eventually go bad if not fall off completely. Good luck with the repair. It should be straightforward. You might want to replace the belt with a new one. At my age, I'm considering suspenders.

Good for you. Snugging up the belt is pretty easy. But since it's so loose... if you don't know when the last time it was replaced... now is an excellent time to take care of that.

Belts are cheap. Keep the old one as a spare.

Toss it.

The belt was new on my motor rebuild a year (about 1500miles) ago, the generator issue was about 6 months ago… and I am also considering the suspenders!

OH! And the oil temp cable in the picture was not correctly installed back then, it eventually was fixed it.

Posted by: windforfun Aug 30 2023, 08:16 PM

That engine looks really sweet!!!

Posted by: CCE Sep 1 2023, 03:00 PM

Ooooo yesss

The wire for the oil temp sender mounts behind the fan shroud. The metal tab, with a hole in it on the wire, goes on a stud.

After I saw that image I had a travel planned so I left the shop with that in mind. So the mechanic send me the video while I was away..

I finally decided to tighten the belt today, after a hard complicated (for me) tin removal, tighten the belt slightly, and it worked fine, no slipping band. But the light was still on, so I verified the regulator… Which sits on top, I installed a dust cap on the relay box some weeks ago, and maybe it has some small short in the base, the lamp shut down after reviewed the regulator.

I think I need to think on how to refurbish the relay box, the underside is cracked and the black material disintegrating

I will reassembly all tomorrow, and try to look for a best solution for the relay base
It will stay without the cap meanwhile.

The underside of the board has seen better days.

But the light is gone now.

The power connector from the cabin does not have the connector that separates, holds, and protects the contacts. Be very careful around this connector as some of those wires come directly from the battery w/o a fuse.

That connector should have a fixture like the one at the bottom of the picture going to the engine.
