    Daughters car, 2017 Jeep Cherokee. She lent it to a friend, so excuse if I don't have all the information. Apparently it would not start for him. He tried jumping it, and apparently was hooking the cables to the small start/stop battery under the pax seat instead of the jump start terminals...

    LED for brake indicator

    70 Duster with Rallye Dash. I want to put LED bulbs in all the indicators. I realize they have to be orientated correctly and got them all figured out except for the brake indicator light. It connects to two pins, does anyone know which way the bulb goes in? I got the steering column out...

    Instrument cluster fixes/upgrades?

    70 Duster, rallye dash. I was having some lighting issues so pulled the instrument cluster out. I believe I had some bad grounds, cleaned them up and tested using a 12v motorcycle battery and it appears they are now good. But while it is out, I am going to inspect and upgrade some things so I...

    When does vacuum advance kick in?

    Got a 408 with a Holley sniper. I’m setting up the ignition, getting my start, idle(18deg) and wot(35deg) dialed in. I never had vacuum advance with a carb but can program it with the efi. Right now I have 40deg set in(still low I think but I’m increasing and seeing how it responds),but at 55...

    short somewhere?

    70 Duster. I disconnect the battery when it sits. Noticed lately that there is a very small spark when I connect it back up that I did not notice previously. I am still learning electrical stuff, so not sure if I am using my Flukemeter correctly or not. I disconnected the - batt terminal and...

    Verify coil

    70 Duster. Chasing down an issue, think it’s my Holley Sniper but want to eliminate any ignition issue. With key in run, I got 12v at the blue Wire going into the ballast resistor. How much voltage should I have on the other side, and is that the same as the coil + stud?

    I need 12v

    i posted last winter looking for ideas to power a Holley sniper. Never got a clear answer, probably didn’t phrase it well. 70 Duster, stock wiring other than Crackbacks headlight relay and alt-batt connection. I have gone through and cleaned/replaced connections so pretty confident they are in...

    EFI power

    I asked this in a roundabout way on a previous thread, so want to clarify I’m not screwing up. Need power to Holley Sniper, 12v while cranking and running. Supposed to draw less than 3 amps. I put a jumper off the blue and brown wires on the steering column connector. See the pink wire in the...

    Wire Alt to batt

    70 Duster. Stock wiring in good condition, only add on will be a fuel pump/Holley Sniper. Saw a thread discussing adding a connection from the alternator directly to the batt. I understand this is to reduce the load on the bulkhead connector and under dash wires. Also see the reason to have...

In my searches I believe these are hard to find items, but I'm not a electrical guy. failing that, I...

    wiring for EFI

    I have a 1970 Duster, 408 with just over 500hp. I’m planning on going efi this winter. I can follow a electric schematic, understand switches and such but that’s about it electrically. The Duster has stock wiring, no modifications. No electric add-ons like electric fans or big thumpin...

    Msd pro billet install w Rev-n-nator

    Have a MSD ProBillet on my sb. Would like to connect it to my Rev-n-Nator, msd says I must use their ignition box. Is this true? Rev-n-Nator uses regular Mopar connectors so I need to splice it in. A). Anyone else use this combo, and B) the msd wiring diagram shows a violet + and green -...

    installed tach, now no power

    Posted a couple days ago about hooking up a tachometer. 70 Duster, rallye dash with the built in tach that was 1000 rpm off. When I was in there I removed a red wire that ran from the bottom pin on the rallye tach to the fuse box, plugged in at the spot where the red arrow is below as I don't...

    Iluminating question

    Adding a tach to my 70 duster, rallye dash. Did some searches and just want to verify. I can run the power wire to the red arrow in the diagram below, and the wire to the light to the connection at the white arrow below and it will dim with the headlight switch, correct? I read where I...

    Tach accuracy

    70 Duster, 340. I have the rallye dash tach. I haven't compared it to another tach yet but some symptoms point to it being inaccurate, if I am correct it is reading low. I have an Accel distributor, pn 59301, MSD blaster 2 with a Rev-N-Nator ignition box. I read on For B-Bodies only some...

    MSD distributor

    I am looking at a MSD pro billet distributor #8534 for my 70 340 Duster. What is involved with adjusting the mechanical advance? Also I have a Rev-N-nator ignition box, would that work instead of the MSD box that says is required? Right now I have a mp electronic dizzy, but it seems to have...

    MSD blaster 2

    1970 Duster, 340 with electronic ignition, orange box 4 pin. I got a two pin ballast, picture below. I got a MSD Blaster 2, 8202. Question I have is do I need to add another ballast per the MSD directions? If the answer is to check the ohm's on the ballast, how do I do that. Between the...

    key goes in, radio powers up

    Installed a radio in my 70 Duster, didn't have one before. It uses the stock power plug. Discovered when I insert the key into the ignition cylinder that the radio powers up. Don't have to turn it on, or acc position. Column is coming out today, what should I look for other than general...
