Proper Order to Disconnect/Connect Batteries M1009

[rgguin]

Is there a proper order to connect or disconnect the batteries on a M1009. I usually disconnect the positive first and connect the positive last, but with two batteries connected is this right?

always disconnect ground first and connect ground last. This is in case your wrench comes in contact with any metal on your frame or body you won't have a major short circut.

And be SURE to remove all rings and/or jewelry before working around the batteries. They can weld to your hide quicker than you think. Wayne

RE: M1009

As said, remove the negative side of the front battery first. Then you can remover the positive of the same battery. I also remove the negative side of the back battery. When I was working on my glow plugs I found that just removing the front battery negative side will still leave voltage from the front battery in the 24 volt system if the negative side of the rear battery is not removed also. Don't ask what I arc welded. I can't remember. The important lesson is to remove the cables from both the negative sides but remove the cable form the front battery first.

Thanks for the help. I had a loud pop and spark when hooking up the battery cables about 6 months ago after I installed my rebuilt passenger side alternator. I think I started connecting the front battery first and the pop came when I attached the positve lead. I could not understand how this could have came from the alternator, but I thought I saw sparks from around the vents. It all happened very quickly. everything worked good until this week. Looks like I am going to put another regualtor in the same alternator. Maybe the pop damaged the new one?

I had popping and hissing when I hooked up my alternator once...turns out the alt was bad.

Greg, I saw what caused the pop when I removed the alternator. The bare part of one of the wires had touched the case of the alternator. I taped it up and fixed that.
