Good Morning all,

well it seems like every 6 months or so this issue returns,

i just slayed that dragon last night and its really getting old. my battery clamps are not going to take much more of this before needing to replace them

 

so here is the low down on the recent findings,

the Ground on the primary battery has the acid build up, the other three did not.

the problem was only presenting itself at speed between 40 and 50 (in the past, this would happen at any speed above 40mph in OD)

 

i have a switch that i can use to kill my alternator (story for another time) so i killed it thinking it could be related to the alternator and the heat we been having. nope issue was still present, i know the alternator shutdown cause the voltage dropped to 12.8 volts

 

 

so what i did to fix the issue,

1) I cleaned the drity post, test drive, same issue. 

2) cleaned the other three, in turn resetting the ECM etc. calibrated the apps, issue was gone

 

so with the alternator out of the system, what would else would be back feeding noise into the system.

i have concluded that cleaning the posts promote a clean power source, and reason the problem goes away.

blame it on the engineering side of me, i want to find the cause.

I know some have seen results with adding the filter, and i may end up breaking down and installing one, but something has to be behind this issue..

Thoughts?

 

Thanks.

 

Holy cow I replaced mine after 10 years. You done very well with batteries. Your cables are shot and should be replaced. When you do replace both the batteries and cables use a little bit of engine oil on the terminals and you'll never have to clean your cables ever again.

 How can you tell by those pictures the cables are shot? I can see the end is shot but cant see the cables themselves.

 

The oil trick works better than anything I have tried in the past.

in my picture, my cable ends are shot, too many times removing and cleaning them, the lead is breaking down.

I am going to order the replacement ends that Genos sells, just going to cut the old ends off, clean and tin the cables an install.

 

I believe i have put my finger in why our control mods have a fit with any noise in the system other they a bad design from the get go.

 

in some cases the issue is caused by a bad diode bridge in the alternator. but in my case. that was not true, my condition existed with or without the alternator powered up and even when it was not hooked up to the system. after thinking about this, it dawned on me, what i was battling was a ground loop. when the connections was bad on one of the batteries, the ground reference was no longer on the same plane across the system. this causes all kinds of issues with noise, any one ever fight an alternator whine the stereo when an external amp was installed? it is normally caused bad a bad ground between the headunit and the down stream components. this is explains why the problem goes away with a good cleaning of the clamps.

I am thinking of running a heavy ground cable across the radiator to cross connect the batteries just like the hot wire. this will guarantee the ground reference is at least on the same level at all the grounding points that connect directory to the secondary battery. even it the connection goes bad (lose or corrosion).

 

I hope to be replacing the batteries this weekend. (had to wait for my non mortgage paycheck).

 

i just wanted to share what i have found cause i did not see it covered else where.

have a great day!
