Is anyone running one of these on a D3?
My new to me D3 has one but I can't seem to get it working
correctly. Instructions spec a 2 amp fuse but these keep blowing. All
connections are soldered. Can't find any shorts. If I put in a higher amp fuse, it works kinda but the second battery is intermittent and sometimes the alarm goes off and the top bank of green LEDs on the the monitor flash for both battery's while the lower LEDs are blank. Bit hard to describe the problems I have with it. Wondered if it something to do with the D3's electrical system.
Thanks.
