Old Meyer help?!?!?

    I am posting this thread for my uncle, with no serial numbers or a model I will try and be as specific as possible. The plow is possibly a late 70's model Meyer mounted to a 1976 Chevy truck. The truck has dual batteries and new 63 amp alternator but is continually draining the batteries, our local Meyer dealer has told him that the Isolator is not necessary with his application. Is this true? What other possibilities could be draining the batteries down in a matter of hours? The truck runs fine and maintains voltage when the plow is not in use. Any help would be greatly appreciated!!!!

    Make sure the up and down switch is not left in float . If it is wired stright to the battery it is hot all the time and when u leave it in the float it will drain the battery

    also i don't think your alternator is big enough to keep the battery's charged up if they are in good shape .the old 3" Meyer motor can draw a lot of amps ! if the charging system is not up to snuff capacity wise it's like pouring a quart of water in a 12" jar ,always hungry and cant get filled up .check all your cable's and up size them if you can .:waving:

    HI, I ran into this same problem years ago.....figured out that upon exiting the truck my knee would sometimes bump the lift lower toggle into the lower position. I fixed the problem by placing a continuous duty solenoid in the line switched that was only energized with when the ignition switch was "on" . No more dead batteries. hope this helps. Neal

    Very simple fix just wire to fuse that is hot only when ignition is on

    Or a switch to power the controls on and off that lights when on so you can visualy see if power is off. What I did in my 69 Ford.
