Postitive battery cable 1972 455

tim72 · June 27th, 2009, 09:08 AM

Does the positve battery cable at the solenoid connection have a duel wire coming off this connector? One would be going to the horn
relay and the other to the positve side of the battery. This would be a one piece cable insted of two seperate wires. I have a power draw which I have not been able to pin down. Battery over night becomes dead. Went thourgh the Fuse checks and nothing seems to be wrong there. I am stuck at the Starter which is brand new as well as the solenoid. The voltage regualtor keeps chirping when I put either the pos or neg wire to the battery. Horn realys the same. If I diconnect the pos from the solenoid off the horn relay every thing seems fine. Bad wire with to much draw?

thanks
Tim

Well my 70 was a wire coming off the positive cable at the battery that goes to the horn relay, not up from the solenoid.
I don't know what to tell you about the regulator as I have a 442 and thus is internally regulated.

72 CSM wiring diagram shows cable from battery (+) to starter solenoid, then one 10 gage red wire from solenoid to the horn relay/junction block on the firewall.

Then an 18 gage red from JB to regulator, and a 10 gage red from JB to alternator post.

And a 10 gage red incorporating a fusible link from JB to the main splice feeding the ignition switch, unswitched fuse buss and main light switch.

The A-body battery cable routing illustration corroborates one feed wire from solenoid post to JB. Now whether or not the JB feed wire is actually made into the (+) cable lug at the starter end, I don't know. It's been years since I looked close at one.

I checked with Fusik and they had a postive cable corect for a 1972. It has the double wire, one going from the solenoid to the battery and a lead from the solenoid to the junction box. This cable end is pre-bent at 90 degrees in order to allow more clearance between dipstick ,exhaust manifold or headers. The wire is $45 but well worth it.
