Doesn't the ECM control the dwell? Would bad solder joints affect the "on-time" of ignition driver? -----Original Message----- From: Vanagon Mailing List [mailto:vanagon@gerry.vanagon.com] On Behalf Of Angus Gordon Sent: Saturday, September 19, 2015 10:15 PM To: vanagon@GERRY.VANAGON.COM Subject: Re: Cause of weak spark? Thanks David, but it's not the ECU. I have a spare which I tried. I'm almost out of troubleshooting time (back to work), but doesn't the ECU control the coil power ground? Why the high voltage?
