Problems with Renogy 20amp DC-DC Charger. Thanks for the suggestion. It had been working fine, so I don't understand why it would all of a sudden stop working the way it is currently wired. However, I am game to try any logical suggestions. I'll try wiring it to the positive cable coming from the alternator.
Also, the green light no longer lights up when the trigger has power.
Thanks for the suggestions. I'll let you know how it turns out.
