12 volt coil hook up

how do you hook up an ignition coil

Car would start, but didn't run well GM HEI's certainly do notuse a resistor. Steal our stuff, we'll kick your teeth in. Every one I've seen, and certainly every one I've hooked up from scratch jp with a ballast or resistance wire between the ignition switch and 21 coil. Take what you will from it but it has convinced me that for my bike, my coil, my plugs I'm keeping the 12 volys on the front terminal and the timer wire to the rear. You are using 12 volt coil hook up out of date browser. The coil will say that it's internally vollt. Tradenames and Trademarks referred hok within Yesterday's Tractor Co. None of these trademark holders are affiliated with Yesterday's Tractor Co. I'll be especially curious about the spark with the primary connections in the two different configuration.

If it is electronic ignition with the external msd coil, you should not have to run the ballast resistor.

Panhead and Flathead site. I'm just about finished putting her all back together. I bought it with a round 12 volt 12 volt coil hook up hung off one of the downtubes so I bought a replica 12 volt coil from NOS Parts but it has no markings on the terminal at all. Before I burn it out that would be my luck, lol I just want it confirmed by someone using their coil that when in the mounted position the primary terminal to the rear of the bike is for 12 volts and the terminal towards the front is for the timer wire.

I also have a question about testing for spark. If I have 12 volts to the correct low voltage terminal and the timer wire hooked up with the points closed and I manually open how do you hook up an ignition coil points the spark plug should fire, right? With the coil mounted the battery voltage coming from the switch should connect to how do you hook up an ignition coil front left terminal, the wire coming from the circuit breaker connects to the rear right terminal.

The coil will work either way and it will not harm it to connect it "backwards", it just changes the polarity. There has always been an argument about the affect of polarity on the intensity of the spark and life of the plug but I've never been convinced that it really makes any difference. Just like the the plug wires, some guys believe that the front cylinder should be connected to the rear terminal on the coil.

Its a wasted spark system and it should not make ANY difference at all. Your test method is correct, every time you open the points the plugs should fire. Try connecting the primary leads on the coil both ways and see if you get a fatter spark with the ignition wire connected to the front terminal, let us know what you find. I can't wait to get home now and put to practice what you stated. I'll be especially curious about the spark with the primary connections in the two different configuration.

I will certainly report back what I find. I have one of those thumb screw adjustable spark "testers" so I might actually be able to see how big a gap the spark can jump in either configuration, rather then just observing the intensity on a spark plug. The drawing is from the Clymer's Panhead Manual that's been in print forever, and it 12 volt coil hook up always been wrong.

Take a close look at the coil in the drawing, the mounting bracket is facing the viewer of the drawing which would actually reverse the positions of the terminals when mounted on the bike. The text, however, is correct. In every factory shop manual, for all twins which use a square coil, the text instructions all tell you to connect the lead from the circuit breaker to the rear terminal on the coil.

It is probably the best and simplest explanation of plug polarity that I've seen, thanks to the folks at the MG car club. I did notice that the picture was backwards-chalked it up to "artistic license". Of course, I will now have to go check my bike to make sure it is hooked up per the text, and not 12 volt coil hook up picture I have heard about the coil polarity making a difference before, specifically in regards to Farmall trractors, but I had never seen any kind of explanation before-thanks for posting that link!

I didn't get to my science project last night. A close buddy with a problem needed a ride to the ER and it took hours. Lucky he's ok, but I didn't get home until like 3 am. Take what you 12 volt coil hook up from it but it has convinced me that for my bike, my coil, my plugs I'm keeping the 12 volys on the front terminal and the timer wire to the rear. I was going to mention that the reproduction 12 volt coils may not be wound in the same direction as the OEM units, but it looks like they are.

At least yours is anyway. Your connections will be exactly like the shop manual instructs. All posts 1 day 7 days 2 weeks 1 month 3 months 6 months 1 year Sort by: Author Post time Subject Direction: Who is online Users browsing this forum: No registered users and 6 guests.

The Ignitor is designed for 12 - Volt negative ground systems. 2. . Connect a jumper wire from negative (-) terminal of the coil to a good engine ground. 3. my '54 FL is 12 volt. I'm just about finished putting her all back together. I bought it with a round 12 volt coil hung off one of the downtubes so I. You can actually hook your coil up backwards and it will still run. Think about it, it's just a Does the coil need 12v constant or just on start up. It pretty much showed the same as when hooked up correct. . have about 20, volts out of the coil secondary and if you pulsed the 12 VDC.
