I have no spark coming out of the coil. i put a plug in the main coil wire and still had no spark?

Question

no spark at all. every thing else electrical in the boat is brand new. i think the coil is the orignial. the boat is a 1989 renken with a 120 hp. 151 cubic inch motor.

Answer 1

If there is no spark,the first thing you need to check is power

to the coil.With the key in the on position use a 12 volt test light and check to see if there is power coming to the positive

side of the coil.If there is power there check the other side to see if power is there also.If not the coil is no good.Now if you have power then either the points or the condenser are bad.If

no points and condenser,then the pick-up in the distributor is bad.This should solve your problems.Good luck.

Answer 2

No spark out of the coil means bad coil.

Answer 3

Just to be sure, you have the plug you're testing with grounded right?  If you do and still have no spark sounds like either the coil is gone or the distributor (does your application have a distributor?)...  if you're coil is original, I would try replacing that first.

Answer 4

Does your boat have a emergency cutoff at the helm.  If so it will ground the coil.   First remove the purple wires from that side of the coil, then use a Jumper wire directly from the + pos. battery terminal to the + side of the coil.   If there are two Black wires and a gray wire on the other side, temporarily. remove the gray.   To check spark Champion and others make an inexpensive spark checker.  You can also clip a timing light to the coil wire and it will flash when you pull the trigger.  That will tell you where the problem is.
