A friend of mine said he read that you could run a seperate circuit for the head lights on my old Mopar rr, and the lights wouldn't pull down when you come to a stop light. Can this be done, and if so do you have to be an electrician to do it? thanx jys
Before you go through the hassle of installing relays that may not help the problem. Check this out.
I think what your friend is talking about is a relay. This way, power for the headlights doesn't go into the firewall, through the switch, then the bright switch, then back out to the headlights. I've been told it's a very simple installation, and it improves headlight efficiency greatly (or, they won't dim as much at stoplights).
Do you have any part #'s for the dual field alt.? Will it work with stock alt brackets on my 71 383? Finally does it look different from the 71 alt?
I have a dual field alternator/solid state regulator on my 67 Charger and the lights still dim at idle. I may have to try the relay trick.
Go here..spells it all out.
thanx 69 1/2 Sixpack Bee, the article lays it out great. I think I'll do the relay deal.
thanx again to everyone who answered. jys

I just re wired my headlights to pull off of my battery directly instead of the ignition.It is a very simple,but sweet upgrade,just requires a Bosch relay and Carquest pigtail assembly and some wire.takes about 15 minutes.Now my headlights and heater etc. don't draw their power off of the ignition anymore so when my cars warming up the heater and lights work at full power no matter how low the RPM's are and I only had to splice into one wire on the harness.I amvery pleased I must say(ED Grimly voice)!
Relays sold by lots of people. Hella brand is part 34rd 960 388-46. Also used as a starter relay on Harleys and can be found at bike shops as Custom Chrome part # 17060. I believe it may be the same one used for power antena. i did this to 69 B body with halogen headlights to save the headlight switch. Plums diagram is right on.
