Wiring alternator Hitachi LR180-030C

I have a Yanmar 3JH4E with a Hitachi Alternator LR180-030C. I'm looking for a connection D+ or 61, (STA) to connect a new relay that separates the starterbattery from service batteries. Can I get help finding the right connection. regards Martin

Re: Wiring alternator Hitachi LR180-030C

I therefore need a cable that has power when the engine is running, but not when the engine is off.

Is the D + the right connection (2.5mm cable)??? This cable controls the relay!

Please, can anyone help me to find the right connection. When the engine is running Im only charge the starter battery.

I like to use an oil switch

NO, closes at 5psi. That gives you power only when the engine is working

Re: Wiring alternator Hitachi LR180-030C

The manufacturer (Skyllermarks, a bosch relay) tells me to plug in D+ that controls the relay. I trust the manufacturer and would like to find D+ on my alternator (if it exists).

I do not understand the function! I do not think that there is voltage on the D+ i when engine is running.

As I understand there may be other problems to connect the relay through various alarm lamps.
