my alternator is very likely deceased
hello you lot, got a W reg sv, but its off road at the mo, it looks like the alternator is clapped out, its just killed my third battery, RAC tested for a charge, and there was,nt any
how easy is it to replace, and where would I find a new/second hand alternator, or a local expert ( also timing chain rattles on tick over after a run out ) I have read through a few post, but it seemed to go off thread, so thought I would start my own thread, thanks in advance for any help or tips I am reasonbly caperble, and have a good tool kit ( I am a machine setter ) the bike does have a "data" imoborlizer, and live near Chester ( north east wales ) Last edited by basilyoung; 15-07-12 at 10:27 PM.

Re: my alternator is very likely deceased
The alternator produces the power, (~80V AC) and the regulator/rectifier brings that to DC voltage at around 13V.
So if you're getting no power, the first thing is to take the 3 wires from the altenator and check if, when the engine's running, you're getting AC voltage, then check if the Reg/Rec is doing a decent job of converting that to something usable. Do a search on here for charging circuit test. You'll find the numbers. In cars the rectifier and alternator are often built into the same component, so you'd swap the whole thing out in one hit more often than not. Jambo

I asked the question on here and was told how to check the voltage myself to find the alternator was putting out ~80+ volts but the reg/rec was receiving the voltage but not sending any to the battery, cost me £40 to fix with a new reg/rec. I think the RAC tend not to know what they are doing with bikes after asking how to test on here I found he was testing from the wrong place anyway. |

Re: my alternator is very likely deceased
I had similar problems which turned out to be the reg / rec.
Have a look at http://forums.sv650.org/showthread.php?t=177418 - in the second post flymo posted a link to the troubleshooting guide which should help. |
