Open 12 V switch on Yanmar 4JH4-TE
Yanmar 4jh4-TE reduces the 12 VDC voltage from the starting switch to the engine Oil switches, relay or other switches, to 5 VDC. My Smart Regulator asks for: "It must be turned on with a normally open oil pressure switch, ignition relay, or other switch that has no other loads on it to cause a voltage drop or "sag". The switch/relay should produce 12 VDC when engine is running.
I have been advised by a Yanmar dealer not to cut into the harness. How do I connect the alternator "Smart Charger" to the Yanmar?
