When finishing up the wire harness installation this past couple of weeks it became obvious that the car is wired with a 100-6 harness, not the 3000. There are a few subtle diffences. I kept trying to follow the 3000 "early cars" schematic found in all the usual repair books.
Fortunately I took detailed notes and photos as to what the wire colors and connections actually were before disconnecting anything.
For instance, my car, HTB7L5101, a very early BT7, built in November of 1959, has a push button starter. Kind of neat and old school (but not very safe). The "early cars" schematic shows the starter solenoid circuitry as part of a multi position keyed ignition switch. The routing of the power to the headlight switch is a bit different as well.
So, (attn: John in St. Louis), on other BT7 cars, do you have the button starter as well? Or is my configuration more of a BN6/4 carryover?
Also, to add a bit of info, I installed three new fuse locattions. One on the power input side of ingnition switch (15 amp as present), one on the power input side of the headlight switch (20 amp at present, and I run the junk bar driving lights off it as well), and one right in the brown main line at the solenoid/battery cable terminal (35 amp at present). This covers it all. Since I only had one Lucas horn in terrible shape, I installed a compact set of electric boat horns off the right side horn bracket instead of originals. These are plenty loud and don't draw nearly the power of the originals, so I put a 30 amp fuse in for the horns in the origianl horn fuse location.
