The way it was wired originally the white wire with the black stripe being plugged into the solid tan was causing the horn to come on at 96 degrees.
The correct way now the solid tan wire plugged into the other solid tan causes it to come on at 203 degrees apparently from this article. The...
I figured it out !!! The tan with stipe goes to the white with stripe and solid tan to solid tan , no more overheat alarm after a few minutes of idling and the temps are still in the 150 range behind the thermostats. I tested the tan to ground and the horn sounded so I believe it is fixed. This...
Does anyone have a diagram on the wires on the port side sensor in the head with colors , I have a dark tan wire that was hooked into the white wire with a black stripe and I have a light tan wire with a black stripe hooked to a light tan , it seems to me these might be backwards causing my...
I will try pulling the thermostats tomorrow and look at them , wouldn't the head get a lot hotter than 150 degrees if the thermostat was stuck closed ? I am leaning more towards the sensor in the head being bad instead of the thermostats but it could be anything I suppose.
Ok I put my center console on the water for the first time since owning it for 7 years , it has been a long rebuild process on the hull but it finally hit the water. The engine is a 1990 Johnson 125 ( J125ESXESS ) the issue is after idling for 4 or 5 minutes the overheat alarm was sounding , I...
Yes it has solid thermostat housings from a late 1980's 70hp a long with those thermostats and springs and gaskets. I'm just wanting to double check that it's done correctly , by plugging the hole at the base and keeping the pee hole in the original location.
I have to test my overheat alarm...
I have a 1990 125 Johnson ( J125ESXESS) on my cobia and I need to see if the water valve is bypassed correctly because they are no longer available. Basically the valve has been removed and the port at the engine base ( where the water control valve used to get it's supply ) has been plugged...
