Are the park lights supposed to work irrespective of whether the engine is running or not? Did the 37 have stock park lights? When the engine is running I have 8 volts at the headlights is this normal? http://i1260.photobucket.com/albums/ii568/37Chev/Truck/20140823_165148_zpsxob0lsta.jpg | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | park lights were inside the buckets with the pre-sealed beam headlights, external ones started in 41, if yours has been converted to sealed beams, wouldn't hurt to add external ones somehow ... all lights should work engine on or off, there should be a wire connection to the light switch from the battery, or the battery connection at the ammeter .... not sure on the generator output, but 8V sounds OK .... find a wiring diagram here in the '38 shop manual Bill | | |
