Well I had a new Optima battery, red top. Worked for a year. Then my 72 E Type wouldn’t turn over. I called Optima and they said to recharge the battery in paralell with non-AGM battery. That worked for about 3 months. Hooked up my Dad’s Die Hard and she cranks over. Bought second new battery (non-AGM) and while the clock and interior light work, the hazards will not and she won’t turn over.
Even the red choke light won’t turn on.
Was thinking about replacing the wires that connect to the battery. Was thinking although they look OK from outside, may be compromised internally.
Would love some help diagnosing this issue. Is it the ghost of Lucas haunting me? Bad fuse? Etc.?
First and foremost, I would disconnect, thoroughly clean then re-assemble and tighten ALL battery and starter cable and wire connections, most especially the ground straps from the engine to the body. If it does not even crank with a known good battery connected, there is something wrong in the wiring, switch, solenoid, etc.
