Happened to me 9 days ago.. Converter died.. So since it was Sunday I got a smart battery charger (Deltran Battery Tender but not the little all winter one, this one is a 1-2 amp tender, 20 amp booster 75 amp jump starter and expensive, 24 hours after I hooked it up and hit BOOST it dropped to Tend mode.. IT WILL NOT GO BACK INTO BOOST ON ITs OWN.. but.. well 25 hours later (1 hour after it dropped into tend) I hit the road to Tekonsha MI.. Re-connected and overnighted at the T/A (Formerly Tekon) Truck stop..THis is the FIRST Full service truck plaza and the model for all the T/As Love's and Flying-J/Pilot stations by the way.
Tues I drove car to Marshall with Dead Converter riding shotgun, and back, with a brand new factory Re-furb/re-man riding shotgun.. Works great now.
Progressive Dynamics, Industrial road at old US-27, Marshall, MI.. NOTE: It's not called Old-27 any more they have a new name but.. Well back when I was growing up it was US-27 (I-69 which was farmland then now is also US-27).
238 bucks lighter in the pocket.
