Again, thanks! | | | | Joined: Aug 2009 Posts: 50 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2009 Posts: 50 | Its to my understanding that the wire going to the coil, brings the voltage to the coil down to the 9volts. It appears to be a special resistance wire? Anyways, is there a way to get rid of that wire and still only have 9volts going to the coil?
65 c20 250 I6 | | | | | | ZooKeeper Unregistered | | ZooKeeper Unregistered | Ballast resistor is the only way that I know of. You have to remember though you truck starts on 12volts & runs on 9volts. If you use a HEI dist you need a full 12volts for it..Joe | | | | | Joined: Aug 2009 Posts: 50 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2009 Posts: 50 | i know thats how its supposed to work.
