Re: 2006 DS IQ charging troubleshooting help
It's not the SCR that is causing an issue. Something is causing voltage at the charging connection to drop a little over 10V.
I got around it by disconnecting the overall negative off the charge post and putting in a 12 AWG jumper from there to the overall battery negative. That effectively directly connects the charger to the main battery lugs. I still need to use the jumper off the grey wire to control the relay in the battery charger.
