Maybe someone has had this problem??
I was driving to work this morning and when I applied the brakes, my lights dimmed and the voltage regulator went crazy!
When I applied the gas, all was well??
Any help at all??

It sounds like you have on or all of the following:

1. Bad ground from the battery (clean them and reinstall).
2. Bad battery (if it is 5'ish years old replace it).
3. Bad altinator (ONLY REPLACE WITH OEM UNIT! If you buy a cheap alt you will have problems again within a few months. Isuzu's only like factory alts).
