67-72 not charging...WHY?

[ebry710]

If the charge light filament is the regulator for the regulator, what can I do to replace the light?

All that has been said is true.
- My 7 gauge cluster doesn't have the charging light.
- My old 3 gauge is on pieces and I do not have plans to use it again.
- The wiring harness for the two clusters are different.
- The charging light for the 3 gauge cluster is modular and cannot be adapted to the 7 gauge cluster.
- Currently, the resonance sound coming from my regulator is sounds an alternator with a bad bearing and the sound varies with engine speed.
- My alternator is running at a continuous 14.5 volts.

Obvious I have to re-examine my cluster upgrade, but I cannot use my truck with an with an over-amp'd alternator. I do not plan to use the stock gauges, just the stock design with after market gauges.
