Time is money when using a generator to recharge a battery. If a charger does not have a correct voltage profile you pay for it in wasted fuel. With a manual Megawatt, a 36 amp model I guarantee I can fully recharge a battery in One - Third the time it takes your WFCO. With my big manual charger I slice twenty minutes more. No brand of automatic charger can do this but trying to make a WFCO into an optimum charger is like hiring a one-armed brick-layer. Or buying Lucas electrical parts to gain reliability. An oxymoron with oak-leaf-clusters and diamonds.
