Title: weak spark Post by JohnsonLager on 02/29/20 at 12:00:27 I'm getting a weak spark and misfiring.  I just replaced the coil and same issue.  I'm reading 10.6v at coil and the same on the plug going to the CDI. Battery is reading 12.6v Any initial thoughts or suggestions?

Title: Re: weak spark Post by Gary_in_NJ on 02/29/20 at 19:27:53 Is the battery reading 12.6VDC at rest or with a running engine. If that’s with a running engine you have a charging issue.

Title: Re: weak spark Post by justin_o_guy2 on 02/29/20 at 21:57:23 Losing two volts between battery and coil is not okay. Check connections under the tank, if not almost falling apart, then disconnect, inspect, a dab of dielectric grease, Check the ground on the right side case. Good luck

Title: Re: weak spark Post by JohnsonLager on 03/02/20 at 18:28:30 There's a connector by right by the battery, I think the wires were yellow/green and yellow/orange maybe? and it was coming loose and really dirty.  I cleaned it up and cleaned up a bunch of other connectors and it's running better than it's ran in awhile. Thanks.

Title: Re: weak spark Post by batman on 03/03/20 at 22:34:09 I would still check the battery ground at the casing . It's on the right side about 2"above and 2"in from the oil level site glass. the motor is also a ground ,it carries the ground that allows the battery to charge , the starter to run, and the sparkplug to fire.

Title: Re: weak spark Post by JohnsonLager on 03/08/20 at 14:51:24 battery ground by casing looked good to me but I cleaned it up anyways.  Currently, I'm getting 12.9 at battery and 12.1 at coils, so I significant increase.  BUT... I am getting a weak spark problem again, I made a second post because I think it's a different issue going on http://suzukisavage.com/cgi-bin/YaBB.pl?num=1583703889/0#0 Thank you everyone for the help

Title: Re: weak spark Post by Armen on 03/08/20 at 19:19:53 Can you take a read while the starter is cranking? And what is the voltage at idle?
