Figured better do a quick check on my “fuel metering solenoid” before replacing the transister that drives it. Used the 2 intake heaters wired together in parallel as a current sink in series with a headlight bulb ,15A fuse and the removed solenoid. The solenoid seems to operate fine with 12v applied. Still waiting for the transister. Thanks for all the input guys.

New to this great forum. Just wondering if anybody knows of anybody that has had long term success after replacing the transistor in their vp44 module??? I am referring to the “injector pump fuel valve” drive transistor that overheats melting its connection. Anyone know what the original transistor was that Bosch used? If so please let us know what transistor replacement you used? Did you solder or use an adhesive to secure and provide the necessary heat transfer? Thanks, Gary
