BX2660 and I Really Hate Electrical Issues

[Gouchybear]

HELP, PLEASE!
I have a 2009 BX2660 with a total of 165 hours on the clock and it has developed a nasty habit of blowing a particular fuse (15 amp fuse #3 in the fuse block which is labeled "ACC") whenever I turn on the headlights. This all started after I installed a digital voltage/amp meter connected directly to the battery, no wires were tapped, spliced or cut. Since this was the only modification I made, I disconnected the meter thinking this would resolve the fuse blowing issue. But it didin't.

Has anyone else had this issue? I'm not very good with electrical problems so any advise on how to go about testing wires/circuits would be welcomed and appreciated.

Thank You!

it’s possible that there might be an underlying problem with the wiring or connections. From my experience, check all ground connections related to the ACC circuit. A bad ground can cause intermittent issues and might lead to a blown fuse. Are your headlights function properly?
If the headlights are drawing too much current, it could blow the fuse. You can use a multimeter to measure the current draw of the headlights when they are turned on. Check other components. hope it helps

Which DVM/DAM did you install ? The ones I bought measure current in the ground return NOT the 'hot' side so I'd like to see how yours installs.
Will need to find the wiring diagram to see what else other than headlights is on that fuse. 15 amp is a lot for 'just' headlights ! At most, maybe 5 amps for 2 '1157' power lamps.

OK, found possible wiring diagram... and the headlight switch also powers the taillights when 'on' as well as a dash light I suspect a short in the wiring,so carefully inspect
