Mopar Electrical Diagram. Look right ta you?

I just finished putting a 273 in my 51 plymouth and am getting ready to wire it up. I made this diagram from 3 others that I found and I would like yer input on it. Seems right but I could be totaly off. Thanks in advance for yer help. I really appreciate it.

 

You're good to go with that schematic, except you need to run the wire from the votage regulator to a switched power source, otherwise you will kill your battery. Move the one that goes from the voltage reg back to the ignition switch to "IGN" istead of "BATT".
Got it?

 

Sweet I'll be cruzin next week. Thanks man!!!

 

The starter relay for Mopars is different than the one for Fords, it's a lower current relay with more terminals. Also there were a couple different ones, depending on if it had auto trans(?)



Might be time to go back to the drawing board for a few minutes...see if you can get the right part, and figure it out.

 

Yeah, there are a lot of ways to wire it...probably the easiest would be to skip the starter relay, and even the resistor bypass. Just go straight from the ignition switch S terminal to the starter S terminal. Also from the ignition switch I terminal to the ballast resistor to the coil.

If it has a hard time starting when it's cold or whatever because it doesn't get enough juice to the coil while cranking: add a Bosch relay, powered by the S terminal on the ignition switch, to connect the + coil wire to power.

 

So are you sayin remove the relay alltogether and go straight from s to s and I to resistor then coil and then just connect the alternator directly to the battery and the battery to the starter? Also I am runnin a 904 automatic. Thanks for all the input guys.

 

I'll see if I can find any info on that jeep solenoid. How big of a diode would I need to run the bypass off the s terminal with the mopar solenoid in the pic? Also on that solenoid the neutral safty switch center terminal would just go to the screw down terminal and provide a ground, since I have no backup lights right?



Is this the relay you are talking about 440roadrunner? If so how do I hook it up?

 

The transmission will have a neutral switch on it. If it's from 68 or later (I think that's the cutoff year?) it will have three pins. The center pin is the neutral safety switch, the outer two are the back up lights. If its an early one it will just have a single connection that is the neutral switch. You would connect the neutral switch to the connection on the Mopar relay, it will ground it when the trans is in park or neutral.

But yeah, I was suggesting just running the starter right to the ignition switch, without a relay. Not sure how much current the Mopar starter draws on the S circuit, but my guess is it's not more than 20 amps, and the aftermarket ign switch should be able to handle it. It would be better to hook up the neutral safety switch, so see if you can find a Mopar starter relay for it. I don't think a Ford or Jeep relay is really what you want.

 

Thanks. The diagrams will really help. I've never had ta wire from scratch before if ya can't tell. Kinda leaves me scratchin my head.

 

Points or electronic dizzy? Try this one:

I looked thru my Chrysler shop manuals...1981 full size van manual shows that 5 connector relay, the terminal next to the battery connection at the top is a resistor bypass! should solve the problem...just connect it to the coil + terminal (be sure to also install the bypass resistor)

 

pretty much like this, eh?

 

You guys rock!! I'm gonna buy an aliance membership just cause this info is worth more than the $50 alone, and thats not counting all the other stuff I've gained from here. Thanx Ryan! I'm sick right now but as soon as I wire it and fire it I'll let yall know.

 

I go for content, not appearance...

and using tinycad is too much work for me
