i have a 2005 525efi. I want to install a battery charging isolator to charge multiple batteries. Where is the charging wire located is it landed on the starter main power lug?

It does go back to the starter, depending on your application and rigging, it may be better to disconnect it at both ends and run a new wire to the isolator from the alternator. I believe it’s an orange wire.

Is this a single engine multiple battery? Or twin engine?

Isolators work, but a Automatic Charge Relay (ACR) does a better job. The ACR automatically connects to charge the battery(s) and disconnects when charging stops or if a battery goes bad (shorted cell or other).

I have 6 or 8 gauge running from my alt. to the isolator charge post. Funny this came up... I'm switching from the diode style to digital soon. My iso has seen better days. Going with the Promariner #23126 1-alt, 3-battery 130amp
