help! i have no spark at the plugs trying to get the boat on water before summers over. i think it could be the amplifier but i'm not for sure<br />backyard mechanic
i have a 69 johnson 85 hp that had a blown fuse that caused mine not to fire. i hope its as simple as that.... but if not...... i can tell you the voltages to check at your amplifier if needed. good luck
thanks for the info. i checked the fuse at the terminal block and it was ok i also checked power from the red amp wire<br />to the blue ok there too i clip onto the ground wire (black w/ stripe) and then touched the ground<br />on the coil and i got spark at the coil and also at the number 2 cyl. i'm not for sure what this means but the spark must have went through the distibutor and back to the plug?? electronics are not my strong point. mechanical either ha ha<br />any info would be greatly appreciated. thanks again.
You have two pairs of points under the flywheel. The lead from the points to your powerpack will go ground, then open, 4 times each flywheel revolution. The pack fires when the points (it's either open or close). Check the lead going to the points (change in continuity as you rotate the flywheel) & see what you get.
