hey all, i have a meyer E47 (2) toggle swith set up on my 84 dodge w150. the problem is, everything works fine until i hit the 2-3 hr threshold and then the "electrical contact" of both switches (up/down, left/right) is, at times, "temporarily unavailable". if i increase the rpm's, it will power the plow. both switches are brand new and the truck just came back from an electrical expert who replaced some cables/wires and cleaned numerous contacts and/or grounds. i was told the electrical system IS charging AND up to snow plowing. however once again, after 2-3 hrs in the truck constantly working the switches, i have to (sometimes) rev the engine in order to get the switches enough power to move the plow. the movement in any direction is NOT slow or weak... just "touchy" AFTER 2-3 hrs working the switches. i have read alternators do not charge (well) at idle... could it be my alt. is not powerful enough? could the selenoid cause intermitent failure and/or hesitation or is it a part which will work (properly) until total failure? also i "piggybacked" power (to switches) from a fuse in the fuse block... could this be my problem... too many accessories on one circuit? should a plow have a dedicated curcuit? thanks, looking forward to hearing from you all. have a good one.
