450: Battery Isolators/Alt voltage drop

[Fearnow]

L450: New battery isolators installed, but charge from alternators dropped to 5 volts. I bought the boat without isolators and the only charging wires were from the computer harness, but producing 14.5 volts. I followed the schematic, but may have missed something?

Use an ACR / VSR not diode-based isolators

What diode based isolator drops the voltage 10 volts?

Something else going on here. Did the OP make a schematic? Post it.

Finally figured it out. They are Cristec isolators. Apparently the alternator needs to see voltage before giving voltage so I pulled off an accessory from the ignition.
