Coil Wire
Noticed that my high tension coil wire ( 47 flathead 6V) has a butt connection between coil and distributor. I’d like to replace it. I’m not familiar with the rubber boot that it enters on distributor side. How do I access the connection and what type of connection is it?

Re: Coil Wire
The old Packard coil wire was the best. I think it is still available. G.M.

Re: Coil Wire
Always have trouble posting pics. The high tension wire goes from bottom of my old style coil into a rubber boot that is in line with the metal tube with plug wires. Apparently this is where it connects to distributor. I want to replace the coil wire but can’t figure out how it comes apart. I’m trying to troubleshoot no start issue which I believe is a weak spark. I have cleaned the ignition switch and I measure about 5.4 volts at coil when switch is “on”. I don’t want to just start replacing parts. I am going to try jumper from battery to coil to rule out bad switch. Car runs perfectly… when it starts.

Re: Coil Wire
It's possible that "butt" connection is a radio noise resistor
--black cylinder that the wire screws into about inch and half long |

Re: Coil Wire
Took resistance measurements on the coil. 0.6 -0.7 ohm low side and about 8500 on high side. Is this in the ballpark? Like I said, 5.4 volts reading at battery side of coil with ignition switch on. Guess the next thing I’ll try is direct wire from battery to coil.

Re: Coil Wire
The resistance of the 6v coil appears ok. However voltage at coil is normally in the 3.5v to 4v at coil going through a resistor.

Re: Coil Wire
Replaced ignition switch. Still not starting. Guess I’ll try replacing condenser. Could it be the resistor on inside of firewall? How can I test that?

Re: Coil Wire
thats easy just with a jumper wire jump the two wires on the resistor. Or just jump battery power direct to the coil with jumper wire. Try that, won't hurt anything for a short time test.
