does any one know if the four little bolts that hold the coil to the mounting bracket are also use for grounding the coil? I am asking becaause I want to move it and if it needs to be grounded then I cant put it where I want to.

 

I don't think the coil is grounded, you can always take it loose from where it is and try it before you move it I guess.

 

i think the ground wire is in the harness that plugs into the coild and the 4 bolts are used for nothin more than to hold it into place[8D]

 

who you gonna believe, a fifteen year old who's still learing or an old man of 55? you figure out which is which! LOL

 

LOL, im just trying to help, im not denieng you

 

that's better, you should always respect your elders!! LOL

 

for sure! lol [sm=goodidea.gif]

 

A coil does have to be grounded. Any electrical circuit requires a complete path, hence the name circuit as in all the way around. Any induction coil in actually two coils like a step up or step down transformer, except instead of AC the ignition coil only works by stepping up the voltage based on the field collapse of one pulse. Many ignition coils have the secondary coil (high voltage side) grounded through the coil body, so they do need to be grounded to have an electrical path for the spark to jump to, unless the ground is shared with the low voltage coil. Clear as Mud?

 

I know what you're saying but I don't think the secondary side is grounded except by the current flowing out through the coil to the spark plugs where it jumps the gap to ground. and on the primary side, in the old point systems, the ground was via the condenser which acted like the shock absorber in the system when the points opened which causes the primary field to collapse creating the secondary current surge which fires the plug. I don't have a clue how this works with the new electronic ignitions though and you may be correct and I'm wrong.
If it does need to be grounded, you can still move it somewhere else and just run a grounding wire over to the coil from a good ground point on the chassis or engine block, so feel free to move it wherever you want to put it notso.

 

thanks for the advice, and will do soon!
