I have a 12V DC Generator I built using a Mike's Windmill Shop Quick Charge PMA (permanent magnet alternator) and am electric start Honda Engine (5HP). This has never been used, the engine has never had oil in the crankcase, never been started and the PMA has never been used. The entire generator is mounted on a thick steel plate which altogether is very heavy.
The starting battery shown in the pictures is bad. I can attach another battery to show that the electric start works. The wagon is not for sale.
I designed and built this to charge my battery pack when there was not enough sun in the winter.
I never used it because I moved and no longer lived off grid.
