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? |

@StarBear the Petronix works beautifully in my car. I can literally see the difference on the timing mark; rock steady.
But my experience with the budget Hella unit was exactly as @Lockwodo described. I now have two Bosch solid state units. The old style solid state delivers 14.29v consistently per my cheap multimeter. The new style gives 14.00v constantly. The only caveat I have is that both require a little throttle bump to get the voltage light to extinguish if you have a sluggish start in real cold weather. |
