Speed four nearly set on fire
So, after a week of cleaning, polishing, general tidying up of my S4, the battery died last night after a ride out.
I replaced the battery with the one off of my old SV650 SK8 and it started up fine. Today, I had the bike running for about 10 mins while I had it plugged into tune ecu and smoke started appearing from under the fuse box :smt025 After quickly turning the bike off and disconnecting the battery, I found this http://i43.tinypic.com/zj8mkm.jpg Its the wires going from the alternator, to the rectifier. #-o Any ideas on what caused this?? Has the rectifier failed or is it just bad luck? Plus where can I get a replacement connector?? :confused: Cheers:) |
Re: Speed four nearly set on fire
Difficult to say but it would definitely be worth looking at the rectifier.
You may be lucky but I wouldn't hold your breath. |
Re: Speed four nearly set on fire
Could be degraded connection in that place causing high resistance... voltage drop... this dissipates heat...
But, also check the reg rec just to be on the safe side. |
Re: Speed four nearly set on fire
This is not unusual, those wires carry the current from the alternator windings, if the spade connectors are slack the voltage passes through a reduced contact area. At higher engine speeds up there could be a hundred or more volts passing through those connectors - if they're not perfectly tight and secure getting hot is a certainty. Catching fire is very rare, usually the plastic block melts and then it doesn't charge and the battery goes flat.
I've lost count of the bikes I've fixed with exactly the same problem. |

Thanks guys, decided to upgrade the rectifier/regulator to a FH012 R1 unit as the standard ones seem to fail a lot as it is.
Also bought a new harness and decent connectors for the rectifier to the battery and stator, should do the trick nicely and stop it trying to combust! haha |

Don't feel so bad . That's how I set my ZX6 smoking too.
Mine was road salt build up .Luckily yours was at home. |
