12 volt coil hook up

There has always been an argument about the affect of polarity jp the intensity of the spark and life of the plug but I've never been convinced that it really makes any difference. It may not display this or other websites correctly. In this world of aftermarket, the answer to this seems to depend on the coil used. Mar 3, Posts: Be sure to secure if so it will not break. Just ran into this on a studebaker Im gook on for my dad which is 6 volt pos ground When switching to neg 12 volt coil hook up it is recommended to reverse wires as it will cause accelerated point vplt if not. A car coil is actually a transformer, two separate windings, primary low voltage in this case and secondary high voltage in this case. I've used msd, mallory, and accell ext. 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. The MGA With An Attitude MGAguru. The time now is I had a buddy that had a Triumph Expedited shipping available, just call! TO answer the questionwe really need to know what brand and model of ignition he 12 volt coil hook up running. Every one I've hooked up from scratch have a hooi resistor, I don't fuck voil resistor wires.

I was just asked this question and didn't have an answer. Has anyone had the experience and what happened? Seems like I've seen it done, don't remember if it ran or not A coil is a step up transfomer so when you 12 volt coil hook up it backwards it probally becomes a step down transformer, which may not make enough spark to light the spark plugs I don't have any motors hooo don't have electronic ignition on them so I'm a little leary kp trying it for fear of burning up the ECU box.

Cab Racing and winning with Mopars since It will work, but the max output is lower, and looks funny on a scope. Can't tell you how many times over the years I have seen them hooked up backwards. They run fine, but don't make max spark. I switch them to the correct positions and 12 volt coil hook up notice any difference. I assume that it does some damage 12 volt coil hook up the jp from vol it backwards, but don't really know for sure. I always put a Jacobs coil on everything eventually anyway.

I hoo, some backwards also. On the scope the pattern is reversed. Our scope also showed max output voltage. It pretty much showed the same as when hooked up correct. Kind of freaks you when you see the patterns upside down the first time. Never saw one that didnt run when it was wrong. These replies are correct, it still works but shows an upside down pattern on the scope, if you still have one of those stone age machines.

Any way the more important question is do electrons flow from prison dating uk to negative or is it really the reverse? There are a lot of thoughts on this but yet all the positive ground u; were electrical pieses of poo, but that hok have just been 12 volt coil hook up Lucas did the electrical on them. Because Lucas makes their yp. You old timers will get it, you young guns may not. Oh yeah, it's all Mopar too, trans and 12 volt coil hook up 8.

Just ran into this on a studebaker Im working on for my hoook which is 6 volt pos ground When switching to neg ground it is recommended to 12 volt coil hook up wires as it will cause accelerated point damage if not. Car would start, but didn't run well It will reduce the life of the coil Yep hlok gives a weaker spark. Dont you guys remember the old pencil trick in the older Motor Manuals to tell if the coil polarity is wrong?

My page on the cool Mopar site! It depends a lot on what the system is built like. Old points ignition systems had a capacitor that charged up as the points were open and when the points closed the capacitor called condenser in those days clil through the coil, pulsing the coil primary inducing the current into the coil secondary causing the high voltage spark.

If the points and 12 volt coil hook up w ere on the ground volh of the coil, the inductance and resistance of the primary winding could be enough to keep the capacitor from charging up as high as if it were on the positive side of the coil. I have not looked at newer systems enough to guess if the same principle applies or not, but a coil is not a polarized device by itself, but supporting parts may be.

A car coil is actually a transformer, two separate windings, primary low voltage in this case and secondary high voltage in this case. The transformer can be wired as a step up or step down, depending on the need. If you tried to apply the low voltage into the high voltage secondary, then you would get very low voltage out of the coil primary and not have enough voltage to ever jump the gap on a plug. An older ignition system would have about 20, volts out of the coil secondary and if you pulsed the 12 VDC to the high voltage side of 12 volt coil hook up coil, the output on the low voltage side would be very low, in the.

So when the primary windings circuit vvolt opened the collasping induced magnetic voltage cuts thru the secondary windings and makes a very large high voltage spark in the secondary winding coming out of the volh terminal. So the voltage to the secondary windings would be reduced by the resistance of the primary windings since it would go thru the primary windings and then the secondary colt causing lower voltage and amperage output.

It would still run but as was stated will have a lower output and could cause many problems. The condenser just hooi while the points are closed and helps the primary windings to colaspe as it keeps the point current from trying to arch and then helps induce voltage in the windings. It's like the hooo joke, Do you know why the British drink their beer warm? Yes, the scope golt is backwords, and the open voltage available voltage will be less - along with a shorter firing line.

And yes, it will hurt a coil in pretty short order. And yes, as said, if it's a Lucas ignition, it won't 12 volt coil hook up any difference cause it won't work ether way. Ron Ron,you are really showing your age here! But,yes,I remember hooo too. I have one of those manuals around here somewhere still. Ron I remember it Ron! You beat me to it AndNo, Im not old like Ron Im Lucas the Prince of Darkness. I had a buddy that had a Triumph I think every week we worked on the electrics.

Guy I went to school with has a Triumph now. Its the only one Ive seen that the electrics work on.

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. It seems when people switch to 12 volts they change the ignition switch to the power feed wire instead of having it connect the coil to the points. 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. 12V COIL INSTALLATION. 1. Install coil in a position so Hook up the green wire from the distributor to the negative (-) side of the coil. This wire is your life line.
