Fitting a charge rectifier/regulator to a 30hp Johnson 2000 model
Submitted by trout1105 on Wed, 2022-03-30 07:56
I have an older Johson 30Hp outboard that I need to fit a voltage regulato/rectifier to so that it can charge a battery to run the bilge pump, sounder etc.
The engine does have a charging coil fitted But instead of just 2 yellow wires coming out of it like on the Yamaha engines this one has 3 wires, 2x yellow and a yellow/blue wire.
Anyone here know which wires go where , I am assuming that the 2x yellow wires are for the AC current But the yellow/blue wire has me stumped.

I remember doing this a few
Cant help on the wires.
I remember doing this a few years ago and from memory the output was bloody terrible to the point that I didn't bother and just upgraded to a decent capacity battery that would last for days on end and when out of the water just left the CTEK charger connected up.

From memory the put out
From memory the put out about 6A, Not much really But plenty to run a sounder and the bilge pump occasionally.
The regulator/rectifier only cost $30 so it is worth a shot.
still trying

Fitted the rectifier/voltage
Fitted the rectifier/voltage regulator today.
All three yellow wires connect to the regulator with a + wire coming from the unit .
All i had to do was earth the - lead and connect up the + to the battery.
14V at 7A, Not a mass of power but plenty to keep the battery charged and run a little sounder and bilge pump occasionally.
