D4 2nd battery charging

Tim thanks and helpful feedback. Moved the car out of the garage to clean it then back again yesterday, rather grubby after the Flinders. That was all the engine time so readings this morning at cold are; Orbital 12.14 and Starter 12.18.

Engine on and readings are; Orbital 14.33 and Starter 14.40. This seems to indicate either a slow current draw from somewhere or poor battery condition??

Regards

Rob

Hi Rob and that a bit more than a slow current draw, it is quite a large one.

Can I make a suggestion, if you are not going to be using your D4 for a few days.

Can you leave the batteries connected via the USI-160 and fully charge both batteries at the same time.

Do not worry about a FLOAT charge cycle, just disconnect the charger once you find it has gone into FLOAT mode.

Then after charging the batteries, go into the cab and switch the switch on the USI-160 In-Cab module towards the LED.

This will put the isolator in IGNITION mode and the isolator will cut-out at 12.7v, separating the two batteries.

Then monitor the two batteries and see if one discharges fairly quickly.

This will help identify the area where the current draw is coming from.

We sometimes go to Grafton or Maclean in it to blow out the weeds, but for a longer trip I am over-ruled and we go in the Disco due the comfort, sound system and my wife can look around and see more as she is 5' 1"
