Re: Rookie Mistake.. - Need help on resistor wire 67 Chevelle SS
Yes, replace either the wire, or put a copper wire in its place, with a NAPA ICR13 porcelain resistor.
BOTH the porcelain, and the full wire resistors have a 1.80 ohm value. To get there, the porcelain resistor has a coil inside the body. The wire is silver stranded wire, with a set length of 7 - 1/2 FEET to get the correct resistance and current loading.
In curring the resistor wire, you changed the loading current to the points, and they will burn a lot quicker than normal. Resistor wires used to be available from stores like NAPA< but, if the wire is replaced with a non-resistor wire, and the porcelain resistor added, the system will sork the points just as stock, fine.
The reason the wire is so long stock is, cars were available with either an I6 or V8 engine, with the V8 coil in the center of the firewall, the I6 had the distributor in the front of the engine. ONE length wire worked for either, but the V8 longer length was run towords the solenoid, then reversed inside the wiring loom back to the coil. I6, over the center of the engine, then down the pass side of the block to the coil
