Friggerpants Posted July 12, 2015 Posted July 12, 2015 After an attempt (and failure to get to chatsworth house today, it seems the alternator is dying.....no warning though.Got a escort home, on a charger rac battery and sought to ripping alternator out. There was a brown cable with a spade terminal attached, and a plug end.....the cable that should be attached to plug end has melted!What did this cable that plugs into the alternator do?I'll assume one cable of it was for the ecu to say no battery (which wold explain why the dash light didn't come on, as its melted) but what about the other? So I took a picture of the back, and I've got my thumb on the terminal for the main feed (I assume) and I'm going to make a mini loom to join to what's left of other loom.......Issue is I have two cables; Brown/yellow and brown/red, and I'm not sure which way round they go? What you think?(Just bought and fitted an Bosch alternator off eBay, plugged in the main brown feed and it wasn't chargining my battery when I swithced engine on.....FFS, so it makes me think that these little cables should be attached)
russelld Posted July 12, 2015 Posted July 12, 2015 The 2 wire connector has pins numbered 1&2 Pin 1 is the radius end end of the connector and connects to the yellow & brown wire Pin 2 is the flat end of the connector and this connects to the red & white wire. If you need a new connector Get in touch with. http://www.simtekuk.co.uk. They will supply you with a new connector with wires attached ( if you want ) so you can repair your loom. They will ask you to send photos of your old connector and also the back of the alternator to help them identify the correct connector, Let me know if you need a photo of the connector as I have a fried one that I can take a snap of if it helps. Good luck Russ. Ps: was it you that I asked if you needed help at Fenny Bentley this morning ?
Friggerpants Posted July 12, 2015 Author Posted July 12, 2015 Thanks for this Russ. Luckily the connector has a part number on it so I can order one off eBay! (It's a vw part, thought they were reliable ;-)) do you know what both cables do? Thanks again really appreciate this.
russelld Posted July 12, 2015 Posted July 12, 2015 Sorry no I'm not exactly sure, I think as you do that one triggers the dash light but not sure what the other one does. The connectors get fried because they are so close to the exhaust manifold.
Martin R Posted July 12, 2015 Posted July 12, 2015 IIRC, one works the dash, the other excites the alternator to allow it to produce a DC voltage. Should be approx 14VDC with the car running. Check by putting one lead ( Black ) off a multimeter on the metal case of the alternator. The other to the big Brown wire terminal HTH
Friggerpants Posted July 13, 2015 Author Posted July 13, 2015 That'd make sense, no excitment from the cable means alternator was doing bugger all. I've had it runing, and attached multimeter red to post on alternator and black to body and no volts. Russ, it was me outside of fenny bentley, as the cable was melted that's why the dash light didn't come on FFS. Got LOT at Donnington next Tuesday, and Asbourne rotary club tommorow night at Donnington too! Time to bodge.
jako999 Posted July 14, 2015 Posted July 14, 2015 Sorry you didn't make to Chatsworth. I was parked by you at the train station I thought after we push started it it would have been ok better luck next year
Friggerpants Posted July 20, 2015 Author Posted July 20, 2015 Update (before LOT tommorow). Made a harness and fitted based on Russ' advice (thanks again). Now got a working battery light...and a working alternator!.....for ten minutes. Ah well, fitted the new one I had just in case and all is well again....left spark plug cover off though and water got in no 2.....so missing a bit, but warned it up and it's working now, just in time for tommorow.
