SOURCE: Low voltage

what is the condition of the battery cables you are probably onto something about a ground but i dont think your ground issue is going to be at the batteries you may not have a good ground on the alternator. The next thing I would check is ... the alternator itself do you know that you are getting between 13.6 and 14.2 volts out of the alternator, a under charge or a overcharge condition both are bad for batteries.

I would check alternator output first if it is not within the above range you need to replace it

If the alternator is putting out in the range of 13.6 to 14.2 then you need to look elsewhere... you may have something draing the batteries overtime interior lights, electric brake controller for trailor brakes if equipped sound system if anything is getting power without going through a switched circuit this could also be your cause.

hope this helps

SOURCE: 04 Columbia freightliner won't shut off w/

Would you not assume the ignition switch may have
worn out & possibly be a problem

It gets used a lot

Test it

If all power is turned off with that switch & you have a
diesel that keeps running, then you need a mechanic
that knows how to diagnose that issue

We have a 2009 Freightliner Columbia that keeps giving fault code "ecu 128 51d 153". Any ideas on what this is?


not in my range of expertise as commercial vehicle but there should also be a FMI code number to go with the fault code , follow link to the freightliner web site where you can download owner manuals etc that may give you more info on your problem also a freightliner forum would be a good source of info , keep me posted if you wish

2003 freightliner mt45 battery indicator stays on.


Put a volt meter across the battery and if it reads less than 13 volts then it has a problem. The system should be 13.5-14.5dc..... 15 volt max. If it reads low only that idle, the engine may be idling to low, the regulator is bad, the belt is slipping, or the system has to great a load on it while idling(to many lights and electronics). If it comes up over 13.5volts when the engine is revved up then the regulator/slipping belt/ or load is most likely the problem. If it does not come up to the voltages listed above then the regulator/alternator are faulty.
