DevilZ Posted June 27, 2009 Posted June 27, 2009 Hey, I took my z out for a drive today and I had an issue where the alternator was charging as shown on the gauge but the current wont make its way back to the battery as the voltage on my ECU was reading 11.5 and wont go up. After I jiggled a few wires around on the fuse block (thing) in the engine bay and back of the alternator, it came good. (reads 12 and will go upto 13.2 with revs). When I got home I noticed that the yellow wire (the one labled black) on the fuse block in the engine bay (thing?) is getting really hot and smoking. I tried swapping wires but the new wire will also get hot too. I included a picture so you know what I'm talking about. Its the first wire, the yellow (labeled black) one attached to ACC. If anyone knows what the issue is, it will be appreciated. Does anyone else find that wire gets hot? Quote
C.A.R. Posted June 27, 2009 Posted June 27, 2009 They are the fuseable links, John. I dare say you have a rectifier or regulator problem... Quote
Moderators Zedman240® Posted June 27, 2009 Moderators Posted June 27, 2009 The fusible links have to be a specific size; that's why they have the colours printed on the fusible link block. Also check the spade connectors on both the fuse wire and terminal for corrosion. That black labeled wire supplies power to virtually the whole car so quite a bit of current is flowing through and if there is alot of corrosion, it will get hot. Quote

No I dont think its the regulator because I have a new one only about a year old. Its the new type too, smaller solid unit. The fusible links have to be a specific size; that's why they have the colours printed on the fusible link block. Also check the spade connectors on both the fuse wire and terminal for corrosion. That black labeled wire supplies power to virtually the whole car so quite a bit of current is flowing through and if there is alot of corrosion, it will get hot. Yeah when I pulled the connector off there is a fair bit of corrosion on both the connector and the terminal. Do you reckon I need to replace both? I'm not sure where I could get a new fusible link block from. Quote
xa1973 Posted June 28, 2009 Posted June 28, 2009 Simplest way..... I had the same issue on my ZX, I made my own new links, very easy to do, get a set of jewelers files and file the block terminals NB:There was a post on the forum from a member who was making and selling the links for a couple of dollars each if you dont have the materials yourself Quote
DevilZ Posted June 28, 2009 Author Posted June 28, 2009 I think I found what the problem is with the wire getting hot. It's suppose to have black fusible wire, rated at 80amp but at some stage someone has replaced it with yellow fusible wire, rated at 60 amps only. As its a slowburnign fuse its holding up bu will eventually burn out. I'm suprised its lasted the last eight years actually. I think with all the ECU, multi coil ignition, fuel pumps and electric thermo gear i'm running its got a much higher current drawtaking its toll on the already small fuse. I'll swap it to black and see how it goes. Quote
