Questions: I'm thinking about getting an electronic distributor for my F4-134. I don't know if my coil is internal or external resistor type. It has a little writing on it, and I can see it says something about resistor, but not enough to tell for sure. Can it be checked by an electrician to determine which type it is? If it's the wrong type could it damage the electronic distributor?
Question By: FRANK ASHLEY on Aug 22 2022 1:08 PM
Trace wire from coil back to ignition switch. See if you have one wired in.

Questions: How do I know if the coil on my 1960 Willys SW has an internal resistor?
Question By: Andy on Apr 2 2022 10:15 PM
They are typically stamped or you will see an externally mounted resistor.

Questions: I plan on switching distributer on my 59 Willys DJ3a from points to electronic (all 12V) How can you check if the existing coil has an internal resister. Mine just says Autolite, no numbers, it reads 7 ohms across the terminals.
Question By: Alan James Witte on Feb 26 2022 3:44 PM
It should be stamped somewhere on it.

Questions: Should there be a balast resistor before the coil on these F heads? Mine didn't have one and ive been doing a lot of research on the ignition system. Seen where there should be one so it does burn up the pionts? Been trying to get it to run since christmas with no luck. Well i did get it to run for about 30 minutes. Then the next morning I was right back where I started. Bought a spark tester and the spark in the tester is yellow. On all the plug wires. So thinking I've got a electrical issue.
Question By: wayne peaden on Mar 16 2021 12:51 AM
Just depends on your coil. If you coil has an internal resistor then none is required. If it doesnt then you need to wire one in between ignition switch and the coil.

Questions: Got your alternator conversion for CJ2A. Came with a coil that is smaller in diameter. Is this coil correct? #RUC15, #RA1016
Question By: Mel Dunfield on Sep 6 2020 1:41 PM
The ALT12V does not come with a coil. This part number: 933160 is the original diameter that Willys used. Please email to help.

Questions: I installed your electronic ignition distributor and got the coil with it at the same time---I need to test the coil...can you give me the specifications for this coil?
Question By: sb on Apr 18 2018 1:29 AM
The only way to properly test those is with a coil tester. Your local auto electrician will have one.

Questions: can this coil be mounted in any position
Question By: Roger on Oct 12 2016 3:40 PM
I'm sure it could be mounted anywhere on the vehicle as long as you had a proper length wire. I would obviously recommend in the upright position.

Questions: I have a 59' CJ-5 with the original 4-134 F head engine, I thought in the manual it said this was a 6v system, but a replacement coil isn't offered here. Is it actually a 12v system?
Question By: Chris on Sep 18 2013 12:00 AM
We sell both 6 volt and 12 volt coils. If you are 12 volt you need to be using a 12 volt coil. After the mid 50's most Willys went over to 12 volt.

Questions: My 1966 CJ 5 was converted to 12 volt. The alternator starts charging when the engine starts it does not have a voltage regulator. Will that cause my coil to burn out? If so do you have a regulator for the coil?
Question By: Roger on Aug 7 2013 12:00 AM
You were probably originally 12 volt in that year. The alternator you have on the vehicle now probably has an internal regulator. I would have a local auto electrician look at it.

Questions: I just bought a jeep that has been converted to 12 v. Does the coil and starter have to be 12 v or will it run with 6 v equipment. Also, what does the resistor do? It looks like I have a resistor mounted near the firewall.
Question By: Anonymous on Aug 23 2012 12:00 AM
Your starter is ok in 6 volt but it will eventually burn out. I recommend getting our 12volt Hi-torque starter motor.

Questions: I have a 1946 jeep willy cj2a when i got it.It didnt have a coil on it so i bought a 12 volt coil. But i dont have spark should i buy a 6 volt coil and will that get me spark...
Question By: peter on Dec 19 2010 12:00 AM
You need to see what voltage you are running in your jeep. I would check you battery, bulbs, voltage regulator can damage your electrical by mixing and matching voltage parts.
