![]() ![]() The issue I am having is the fan comes on as soon as the engine is fired up. Installed relay to the starter relay (all those wires get concealed behind the washer bottle): View attachment 397164 Wired relay based on the description above: View attachment 397163įan secured to the radiator: View attachment 397162 Wiring up the relay to the fuse: View attachment 397161 I am chalking up today’s work as a success on this fan project, but have run into an issue that will still need some diagnosing (and probably a bigger fan). What year vehicle is this and which engine? You will also need to block the heat riser in the open position by tying it down or better yet just remove it. If you installed the EFI yourself, that is probably the source of the excessive heat if the heat riser passage is not blocked. There is an after market intake gasket that blocks the heat riser ports as the heat riser passage is not needed with EFI. Check you instructions, most of the time a heat riser is not needed with EFI. This will cook the EFI unit electronics for this type of EFI or cause it to shut down. If the valve is stuck shut, exhaust is diverted thru the heat riser passage under the carb or in this case EFI. As the engine warms up, the spring weakens and that valve opens. The valve has a thermal spring that closes the valve on a drop in temperature when the engine is cold. ![]() I know some people swear by the three wire set up and its supposed volt sensing ability, but this one wire alternator is dirt simple and since the alternator senses the voltage at the battery and the positive side of the starter relay is less than six inches from the battery (hence not running thru the whole wiring harness to get to the engine bay), I not only have a very simple wiring under the hood, but everything that needs it, gets full voltage and current.Usually on the passenger side exhaust manifold there will be a flapper valve where the manifold meets the exhaust pipe. My headlights don't dim when running the stereo, heater, my electric cooling fans that pull 35amps, or anything else. The one wire alternator works awesome and I have a constant 14.5 at idle at the starter relay. This takes the current out of the factory light switch.Īs you can see all my high amperage draws under the hood connect to the starter relay. inplugged headlights plug in wiring harness (yes its that simple) and mounted the relays. I also wired the wild horses nighlighter, to the positive side of the starter relay. ![]()
