2013 F250 6.7 Powerstroke

[Alumarine]

Hi Guys,
A friend has a 2013 F250 6.7 Powerstroke and he'd like to load test the batteries.
Anyone know the correct procedure to isolate the batteries fro testing?
Hopefully we can isolate them and keep all memory functions alive.
thanks

Disconnect one Bat and load test, then reconnect and disconnect other Bat and load test

If you want to remove both, then connect another Bat to one set terminals using jumper cables

Great, that's what I was hoping. Thanks.
When disconnecting do both cables need to be removed or is one enough?

Ones enough, and doing the ground would be best

Great, I'll let him know, thanks.
Now to trouble shoot the P20BA def fluid heater error.

When my diesel starts having Bat issues I break out the voltmeter and get the truck running. Disconnect ground on one Bat and measure the one still connected, usually 14.5V. Reconnect and then disconnect the other and do the same thing with other Bat. If one won't charge at full rate, that's the bad one. I then replace both

Checked the batteries.
One was bad and the other was really bad.
Replaced both.
Hoping that may have been the cause of the P20BA as well.
If it comes back he's taking it to the dealer.
Thanks for the help!

Unfortunatly it's probably the reluctante tank or heater inside if wiring and connections are good...Also the weather may be a factor false codes in warm weather ..glow plug module can cause it also
The worst l won't even mention

Code came back so he's taking it to the dealer next week.
It's 15F now so I don't think it's a warm weather issue.

Lots of black smoke

Update, dealer replaced the Def Tank/Heater on a recall.
No charge. Worked out well!
