hi,
where can i find my voltage regulator on my 1982 camaro with a 1978 v8???

thanx

is it possible to have a slowcranking starter because of a bad regulator?

Regulator is inside the alternator.

It's possible, but usually the solid state regulators either work or they don't. They usually won't cause problems like cranking slowly. Eventually, the battery would just die. More likely bad starter, starter wiring or weak battery.
