What to do when your generator light does not come on?
If the light does not come on, then reattach the negative battery cable and move on to checking the voltage output check. If the test light comes on, there’s a short in the electrical system. You must first find out where that short/drain is coming from before we can check out charging system.
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.
When to replace an alternator in a generator?
If after replacing the internal regulator/brushes in the alternator does not fix the problem, then the alternator is probably bad and needs replacing. Hang on to the new regulator/brushes and keep them as a spare (most places will not let you return electical parts, if they do, cool deal!). Conclusion.
What causes the generator light to come on in a Speedo?
If you suspect that the battery has a bad cell or two, you can buy a hydrometer from any FLAPS. This simple device checks the specific gravity of the battery electrolyte in each cell. A bad cell can cause the generator/alternator to overcharge the other cells which will trigger the generator light in the speedo.

How does the warning light on an alternator work?
If the alternator has an external regulator, the warning light wire attaches to it in the same way as a dynamo. Again the terminal will be marked WL or IND. Some cars, however, have an alternator which uses a separate relay for the warning light circuit. In this case you should disconnect the wire from this relay.
