True Isolator issue

[SgtGuy6027]

How old is your second battery? You said you replaced an Odyssey, just the primary or both?

The main is still the factory, I replaced the 2nd battery last week.

Backed it up into the garage to get a better pic

If it's still reading zero with the blue light on, the isolator must be bad. That means your 2nd battery was never getting any charge.

Remove the mounting screws and see if you have voltage on the auxiliary side with blue light on.

The customer service and warranty at True or Amalgamated, I think their parent company is called, is first rate.

Just ordered another isolator, when I get it I'll let you know what happens. Thank you for your diagnosis guidance.

Just curious what the voltage is of the second battery itself, without testing at the isolator? I don't think I've every seen a complete 0 on a battery especially since you said you replaced it last week. If it has any voltage at all I would think you could read it at the side of the isolator as long as the negatives were hooked up together. Just curious.

Sorry scratch my last statement, I see in the pic you don't have the second battery hooked up. Hopefully the new isolator will take care of you.

Just installed the new isolator 14.3 volts on both side. Thank you for all you help and guidance.
