What does the Gen / alt light on the left mean?
Don’t make the mistake of thinking there’s an oil pressure problem — the light on the left is the “Gen/Alt” light (generator or alternator, depending). When it comes on it is telling you that there is something wrong in the electrical charging system — the battery is not being charged.
Why does the Red generator light keep coming on?
For the red generator light – see our checkup procedure – all you need is a voltmeter. This procedure will help you decide if a charging fault is the battery, generator or regulator. My 1970 engine is equippedd with an alternator that has an internal regulator. My problem is that the “alt” stays on when the key is off.
Where is the generator light on a 1967 Ghia?
On a 12V car (1967 and on) it’s usually under the rear seat off to the left. In Ghia’s, I think the regulator is in the engine compartment and I believe that’s the same with the Bus. Anyway, check and make sure that the wires are on good and tight and not burned or damaged. Replace any wire.connector that looks bad. Battery.
Why does the warning light go out when I Rev the engine?
The third possible problem with a warning light is that it goes out as normal when you rev the engine slightly but comes on again as the engine speed is further increased. If the warning light simply glows dimly it usually indicates the problem is a high resistance somewhere in the warning light circuit.
Why is the Gen light on when the key is off?
If you KNOW that you didn’t accidently reverse the positive and negative cables (even for just a second since that’s all it takes), then you have to start looking elsewhere. Although not very common in the way of popping diodes, it “could” be the regulator.

How does an IDJIT light work with an alternator?
The idjit light essentially goes from the alternator output to the battery positive. If all goes well, both terminals are at the same voltage potential and no current flows. If either the battery or alternator are not at the same level, there will be current flow through the light and it will illuminate.
What can I do to keep my generator light on?
Inspect the battery posts, for a few bucks, you can buy a battery post cleaner or use a wire brush and clean the posts and the battery clamps. For about $1.00 (USA), you can buy these little felt rings that you place over each battery posts which helps keep them nice and clean.
