Hi Everyone,
I just installed my A129 Duo tonight with the HK3 hardwire kit on my 2019 CRV. Everything went pretty well, but when I went to turn my car on to drive it back to the garage it wouldn't start. TLDR: my battery dropped from 12.2V to 6.8V over the course of about an hour. This is probably a massively stupid question, but is it more likely this was a result of us having the car on ACC power for an extended period of time, or do I have a short circuit somewhere? Or would a short circuit have had a bunch of sparks and melting wires?
We'd used a voltage tester towards the beginning of the install to check for battery versus running power, and I got 12.2V from the battery fuse (#33, driver's seat sliding) and a minute later 11.8 from the ACC fuse (#22, daytime running lights). That seemed like a big dip to me, but I chalked it up to not being directly connected to the battery. After we got the fuses connected and the front unit turned on, we started working on cabling for the power cord and rear camera connection. I think that was about 45 minutes to an hour, and I don't believe we had ACC mode on, but the shop was a bit noisy so I may have missed the signs of more things being on. I doubt the AC was running but I won't bet my life on it. Doors were open most of the time, however.
Anyhow, I went to turn the car back on after we got the wiring done, and the instrument panel was going a bit haywire. It took us a few minutes to diagnose the low battery, and after we hooked the charger up to it we reconfirmed the taps were oriented correctly (we did pretty much exactly what Anthony Mo did in his dashcam install video).
So, is it feasible that running an unknown number of accessories for about an hour could drain a battery that much? Is it possible that we did something that would have caused a short circuit and a power drain? Are both feasible? Or do neither of these make sense and I just have a haunted battery?
