Hello I'm having trouble finding where this fusible link goes I've followed the wire and found that it splits off into two different wires one goes to the power wire to the alternator other one digs into the harness box coming out from the firewall I've used a wiring diagram I found online and it shows the fusible link digs into the starter relay then battery tried both and no luck
What your holding should go to the battery and the fuseable link in between....
If it is hooked up to the alternator shouldn't it be connected via fusible link to the starter relay post and get its connection to the battery from there?
I thought the only fusible link that went directly to the battery was for the hazards... not claiming to be an expert though this is more or less for my own confirmation. I'm actually wondering if it really makes much of a difference.
Well, those two wires, to my knowledge, would not have been hooked together from the factory so that's already evidence that someone has been hacking it up a bit.
Try tracing that wire back to the bulkhead (harness box on firewall). If you do a search for 1984 dodge w100 bulkhead connector you should come up with an actual diagram. I think the first step is to figure out what someone connected to that circuit. If it is the ammeter (space 27) then they did an incomplete fix and/or bypass on the ammeter. I'd be interested to know if it is also still connected to the ammeter.
None the less, running the alternator to that starter relay post with a fusible link is common.
The truck runs just dont think its changing when I touch the power wire with a test light while it's off it's not getting any fire but when I hooked the fusible link wire to the battery while it was off and tested it it was getting fire before I turned the truck on then the wire started smoking so I unhooked it is there anything else it could've maybe been tied into besides the starter relay and battery?
I'm also having trouble reading the timing chain cover I've replaced alot of the ignition components including the distributor before finding out it was that wire shorting out it's close but I wanna hit it with a timing gun but not sure where to set it at on the timing cover it says 12 btc on the inner fender guessing that mean before top center? And not exactly sure where the 12 is at on the timing cover it just has 10-0-10 it's a stock 318
I have not followed the orange one yet but on the bulkhead wiring diagram it says the only two orange wires I should have would be a tempature gauge and ignition start the blue one says it's a ignition feed?
It is hard for me to see what position that blue wire next to your thumb is actually in but that is the one you are focused on correct?
Is it in the slot farthest to the edge or one in from that?
You are correct, that orange wire is the start.
Technically, in stock application, there is not a wire that comes off that harness and goes to the battery so I'm pretty sure that something has been bypassed in your situation. That bypass could be a fuse or even the ballast resistor.
I would say that if you are getting a smoking issue when you hook it up then you are dealing with a ground issue somewhere.
Should I just separate the wires? The blue one I'm assuming i dont need because it still runs and drives i dont believe they where ever hooked up since i owned the truck i got it in June and been daily driving it like that until September i still drive it around town every other week it's really the black wire I'm worried about because it goes straight to the alternator so I dont believe its charging correctly could I separate them and try hooking the black alternator wire to the battery or starter relay? Haven't had time to mess with it's been raining in dallas TX on my days off
If you put a fusible link onto the charge wire from the alternator wire then I would advise that you hook it up to the starter relay post that the main power comes to from the battery. I don't like having too many connections at the battery terminal.
That is definitely not a stock solution so just keep in mind that someone has changed something in your wiring. I often assume that there was a reason why they disconnected it and that reason was probably frustrating.
You can check if the alternator is functioning with a voltmeter. The battery will be around 12V with the truck off. If you turn the truck on and the meter jumps up to around 13 then is is charging.
So I've tried to separate the wires and it doesn't wanna run unless they are together so I hooked both of them up to the battery this time using thicker wire and a different fusible link ran okay and wasnt getting hot but when I opened up the throttle it kept blowing thr fuse so I went to the parts store and the guy there told me the alternator wire needs to be hooked up to a ignition wire in the column also said I could hook it up to the starter but recommended hooking it up to a ignition wire
