relay question
I posted this in adaptronic forum as well, but figured I would post here since it is a general relay question as well. I am not sure if the relay is the issue or the adaptronic really or my wiring.
I have wired up an electric fan to a 30/40 amp relay. The issue is it is not triggering the relay. I have the adaptronic connected to the 86 terminal on the relay. If I unplug the wire coming from the adaptronic to the relay and then connect it it will trigger the relay and the fan comes on. This may be because when I unplug it the voltage increases to 10-12 v. However if it is connected it doesn't get triggered and its sitting at 4v when Aux 6 gets triggered due to water temp setup. I did test the relay with a 9 volt battery and it triggers fine that way. I am stumped here. I haven't ever really hooked these up before. Anyways any assistance would be appreciated. 87 Fan 86 Adaptronic AUX 6 85 Ground 30 battery |
Relay option 1
So I am being a little cautious since I wouldn't want to mess up this ECU of course.
So this is my current configuration. 87 Fan + 86 Adaptronic AUX 6 85 Ground 30 battery I thinking of trying this when I get home. Maybe I was wrong in thinking the adaptronic would provide the voltage to switch the relay. 87 Fan + 86 Adaptronic 30 Battery 85 IGN Power I think this would work maybe. Maybe let the Adaptronic provides the ground when it is switched with water temp. |
Posting answer here as well since I posted this in 2 areas. I figured the fan situation out with the relay and the adaptronic ECU.
This setup worked great with the aux 6 settings. 87 Fan + 30 Battery 12V 86 Adaptronic (ground) 85 IGN Power The Dorman 62-118 fan I used worked awesome as well. I gotta figure out what temperatures to turn it on and off at now. I figured why go to junkyard when you can get this for $75. This is a replacement the old ford thunderbird and mercury cougar fans. It had great ratings on Amazon as well and lots of talk about using this for hot rods. |
