Re: Where to Connect Engine Trickle Charger Reply #25 – May 11, 2017, 10:48:38 pm Quote from: Realmccoy – May 11, 2017, 01:37:55 pmAnother fan of Trik l start. Installed at isolator with easy access to start batteries on my U270. Disconnect negative on house batteries when installing. Don't want an accidental grounding of wrench to chassis. Works for solar, land line or generator operation. Also very affordable. And don't use a wrench long enough to contact the positive pole while losening the negative cable, BTDT with a weird GM terminal clamp style this week. Quote Selected
