MIL after dual battery instal CRD

[fester]

Guys I've done my dual Optima battery instal finally with power disconnected for a few weeks now. Upon firing it up finally I now have the check engine light on and a new fault code of P0620 - Generator control circuit.

On WJJEEPS it gives no further explanation or hints. Can this be related to being powered down for so long. I'm pretty confident that all wiring has been reconnected and that I have earths contacting. I've not blown any fuses or anything else.

Haven't had a chance to go for a drive only fired it up tonight before shutting up shed and heading up to bed. Hoping it clears but curious if I should be looking for anything.

I had the MIL light come on after a battery failure off road.
Not sure of the error but reset it with my scangauge. (could not get the error to com up)

Hi fester,

How's it going with the P0620 code? I'm just about to put in a second battery and am a bit concerned.

Also where have you put the second battery. I'm thinking of in a box behind the front passenger seat but not real happy about that.

Sorted itself out. I have built a dual battery tray in the standard location but using twin Optima batteries rotated 90 degrees. I posted some preliminary pics in another thread, but too late for me to dig up tonight, early start. Have a look is my other threads it's around somewhere.
