Tried to start my car (87 Targa) after a week sitting and the battery was completely dead. Put a charger on it and never would get past 41%. Tried to jump it and the clip was too large on the cables and as I was moving it to get a good connection, broke off a wire connected to it (see pic below). It broke off pretty easily and when I touched the wire to the pos post it sizzled a bit.
The only change I made to the car is installation of the F9 DME and the car ran fine after that.
I’m going to get the battery checked but two questions:
1.) Where can I find in the manual what these wires go to?
2.) Is there any possible reason the DME would cause a drain on the battery?
Thanks in advance for any thoughts.
