    I put a used hybrid battery in and now have no triangle of death but have these lights on the dash and no ready light comes on. What am I doing wrong, I did replace a battery about 5 years ago and but have forgotten what I needed to to to get the car running agian.
    Yes the battery is good and the 12 volt appears to be good, I have double checked all the wiring and made sure I plugged in the disconnect and pushed down.
    Thank in advance.

    For the first start after disconnecting the 12 volt battery you have to push the start button twice with your foot on the brake.

    Try holding your foot on the break for 10 seconds then double press the start button.

    You may want to double check that orange plug, I have a feeling it may not have been pushed in and locked down..

    May I ask how that was determined? I do recognize that you do not have the RTOD, just curious how you know it's a good battery.

    I have an HV battery on my bench right now that, in all appearances, is a good battery. Doesn't even have any electrolyte leaks....but....prior to disassembly, it measures 23+ volts from the (+) main lug to the case and the individual bad module is showing 6.7 volts when measuring to the case. I'm guessing a hidden crack in plastic module case body allowing electrolyte to touch the metal thread insert on the bottom and grounding out. Was bad enough it wouldn't even let the main relays close.
