headlights

Disconnect the 2 wires from the brake switch and check each terminal to ground with the switch OFF and pulled ON. You should never show continuity in off or on. Some repro brake switches have had shorts to ground. If the switch checks out then look at the taillight.

Do you have the teacup light, or the drum taillight?

The drum light has a very different way to run power to the brake bulb, and I can find a picture if you want.

For 6V operation 32/50 cp headlight draws 3.9A for 32 cp and 5.3A for 50 cp, 35W bulb is 5.47A and 25W is appx 4.2A. Need to figure how much Current will be drawn when running headlights, tail lights, dash light and any other accessories. Putting in the higher candle power bulbs everywhere can draw more current than the generator can handle. This is one of the reasons car manufacturers went to 12V. Changing to Led lights for tail lights helps with current draw.
 
well....getting closer. Model A runs like a champ now. Disconnected the brake light relay by the battery, can put on the brakes now without pooping a fuse. But... i can turn the headlight switch one way, lights come on no problem. Switch it the other way fuse pops.....

Sounds like a short may be in the plug at the base of the headlamps. Also make sure the adjustment screw in the rear of the bucket isn't too long and hitting the socket.
 
Prrrrrroblem solved! I have headlights and tail-light again! but i need a new brake light switch. That was more than the problem though. i pulled the headlight wires out of the socket and filed the round brass pins (that were so big the were almost touching), into triangle type shapes with a flat triangle file. Fired it up, flipped the switch left to right, high beams, lo beams, license plate and taillight working no fuse blowing :) but.. like i said i need a new tail light switch then my model a is finally dialed in!
