    I am new to auto wiring and have a question. I am rewiring my 1951 Chevy 3100 and retaining the 6 volt system. I am adding turn signals and purchased a turn signal switch. The instructions/diagram show "to battery" at two locations: one from the + terminal on the three prong flasher, and the other from one of the terminals on the brake switch. What do I do here? Am I to connect directly to the battery somehow, or can I connect to my ammeter. Sorry if this is a stupid question, but I just want to be sure about it.

    I would connect to the ignition switch so they wouldn’t work with the key off.

    The brake light switch positive (to the battery) wire needs to be connected to a constant hot connection, so that the brake lights will operate with the key on or off. the flasher positive connection needs to be connected to key on power, so that the flasher relay only has power when the key is on. Do NOT connect directly off the ammeter for power. The switched (key on power) should be connected to key on power on the fuse block, if it still has all the original wiring, then switched power should be connected at the key switch (ignition switch) to the wire that has power when the key is on with a 15 amp fuse in line to protect the circuit. Constant hot power should be connected to a constant hot terminal on the fuse block, or if its original wiring than it should be connected to the power wire that is supplying the key switch juice from the batter with a 10 or 15 amp fuse in line to protect the circuit. A cheap test light works well for figuring out what wires are what off the key switch.

    And be sure to put a fuse in any connections that aren't already fused circuits!

  7. Plus, MercMan , as Jasper, has had all those questions and more answered on the AACA Forums. Hopefully you guys are believable to him!:D:D

    firstinsteele,
    I DID receive good information from AACA forum - mostly about grounding issues. It's just that I have been getting so many disparate answers/suggestions from so many sources - including the manufacturer of the wiring harness, and the manufacturer of the turn signal switch, that I wanted more information. Remember, I mentioned about getting power from the ammeter; Nailhead Jason told me to NOT do that here; so, now I have discarded that idea (thank you Jason). I received suggestions to have the turn signals wired so they did not activate with the key off, but not specifically how. etc. etc. Sorry- like I said, I am a novice at wiring, and I needed a little more. Besides, this is what I do anytime I am doing something that I am not proficient at - seek information from many sources.
    I do find AACA forum believable - helped me many times. Sorry if I offended.
    My thanks, and many blessings to you all.
