Hello for now, I’ve been having problems with my battery for a long time now. I’ve already “lost” two batteries because they’ve unloaded. A well-known suspected that I have a mass error somewhere. Then I took my complete wire harness apart but unfortunately no find. Now I have decided to plug off consumers and see if one of these will not discharge the battery quickly. Then I plugged out the carburettor heater and see there , the battery no longer sinks to 9 volts. Now to my question, how exactly can I check if it is really due to the carburettor heating before I replace it? Can it really be due to this? I know myself when it comes to electrics really hardly and would look forward to a few tips Thank you already in advance! LG
