I'm having difficulties with the regulator and my mechanic wants to replace the voltage regulator on the relay board with this one that attached directly to the alternator. I've never heard of this on a 914. Is this legit?

Okay. That's what I was thinking as well. I will tell the guy to use a regulator that fits on the board.

Someone did! I remember that now. And I remember at the time thinking "that's cool but it's a bit pricey maybe I'll consider it lat...and it's gone". @hydroliftin , removing and inspecting the relay plate is not difficult. Look for the area below the VR to have gotten hot and the resin maybe melted away. The electrical tracks may even be rusted. This is common with the mechanical VR, as it tends to get hot. To avoid this heat, you can either get a solid state Hella VR (though I read recently that they're NLA) or NAPA sells an Echlin one that can work with some slight mods: https://www.napaonline.com/en/p/ECHVR503 I've mounted the NAPA one external to the board, and then ran a jumper from the plug to the board so the GEN light works (and the alternator gets 'excited' properly). You can flip the stock-type mechanical VR and add the jumper the same way to avoid putting the heat on the relay plate. I actually recommend that for everyone. Greg P.S. Ignore the diode in the photo; that's for my Microsquirt install. Car wouldn't shut off with the key; turns out the Microsquirt ECU is so power-efficient that it was just fine getting power through the GEN light circuit...the D-JET computer couldn't survive on such low current so it was not required on the stock setup. |
