I have a Bosch solid state regulator and have been noticing low and erratic charge rates lately. Swapped it for a nos Bosch mechanical reg that I had in my stash. Charge rate is 13.8-14v now, perfect but, the mechanical regulator gets pretty warm after running for awhile. I measured the case at 130F. Is this normal for a mechanical regulator?
I would like to get a solid state replacement but the Bosch regs cost almost $400. What gives? did they stop making them? What is the currently recommended replacement? |

Wondering if anyone has had this problem before. Car is a '74 2.0. Replaced voltage regulator with a new Hella unit. At 1000 rpm idle, voltage measured at the battery terminals was initially steady at 14.5 volts (too high), and now is fluctuating from 12.5 to 16.5 volts. Is that likely a bad regulator or could a problem elsewhere in the charging system produce that fluctuation?
