Problem with Volvo battery protection system

yeah, you can jump it. easily.

 

You want to have it checked and repaired if it is a rubbed threw wire or a bad conection even you could have a fire.

 

Does LVD overide button help?

first of all I check poor connection, corroded terminals and bad wiring. To jumo LVD relays is easy, but to find a problem....

as I remember you can disable LVD (low voltage disconnect) with sleeper control panel, but not on all trucks.

the easy way to disable LVD is find relay box in battery box and connect all thick positive wires together.

 

we operate European versions and boxes are usually in battery box, splitting positive wires. Seems to me they put all this ###t under the driver's side steps.

 

karicz i had the some proablem in the past is easy the red wire that go to the starter is lose some where check it from the battery to the starter mine was doing the some thing i have friend he had the some proablem in mine situation the screw at the starter where the red wire conect was lose.i hope that helps.

 

i just got into one it is doing the same thing but my voltage is 13.7 running and 12.5 stopped our othe two charge at 14.1 and 12.9 stopped they both have the fridge running all night i cant even have my webasto run for 6 hrs without my fridge . my feeling is the voltage protection ecm is reading the voltage off the truck ecm and wondering if there is access if i was to get into the perimeters on the ecm or where the ecm gets its voltage info ie battery / starter ect .
