Something similar to the Vanagon voltage stabilzer on the >instrument cluster foil. There is for sure a +5v regulator. On Max Wellhouse's Bosch 025 906 022 (which has about 125 cracked solder joints I'm about to start soldering, not counting the ones that Darrell or someone already reworked a few years ago) there are four large three-legged components clipped to the big heat sink. I'd be fairly surprised if one of them was not a +12v regulator. That leaves one for ignition drive and one for FI drive. Yours, d |
