The D3 electrics are certainly a challenge.
There are so many different types of BMM, with the negative terminal in different places. I'd also need to try and get the newest one possible to try and avoid getting a used duff one, or a used one with the old firmware that would need updating. One other possibility, yesterday before I aborted the current test due to low battery I was getting ready to disconnect the alarm siren. I had the siren unbolted, and it was laying face up with the power connection visible to disconnect for around 15mins. Since putting it all back together everything seems to have been fine. I keep going round the same circle, battery, alarm siren, heater resistor, BMM. Could be any of these acting up. This is the current BMM
