Numptie Posted August 16, 2004 Share Posted August 16, 2004 Strange thing ... At the weekend, I drove the MegaBlade in the dark for the first time. At about 8,000 or 9,000 revs, the lights dim and flicker significantly. I've been thinking about this and can't get my head round how this could possibly be. Any ideas ? I have a feeling someone's about to make a point which causes me to say DOH! Cheers, N Quote Link to comment Share on other sites More sharing options...
scruffythefirst Posted August 16, 2004 Share Posted August 16, 2004 What alternator have you got? The standard bike one or a car one? Quote Link to comment Share on other sites More sharing options...
peterg Posted August 16, 2004 Share Posted August 16, 2004 the lights dim and flicker significantly You've obviously got the shift light set too low, change it to happen at 10,500 Quote Link to comment Share on other sites More sharing options...
Blatman Posted August 16, 2004 Share Posted August 16, 2004 Same as Scruffy. Gut reaction says alternator. With all things eletctrical though, a good check of all the earths is a half hour well spent... maybe you've got one rattling/resonating loose at those revs...

Megablade Paul Posted August 16, 2004 Share Posted August 16, 2004 Unless someones messed with it the earths will be fine - I know The rectifiers are a weak point although not sure with the symptoms you have. The bike guys cook them regularly so I went to the trouble of fitting an upgraded one to your car and additional 6mm thick ally plate to aid heat sink. During my 3000 miles in it I never noticed a problem with the lights. Quote Link to comment Share on other sites More sharing options...
Crash Override Posted August 16, 2004 Share Posted August 16, 2004 I've got the Bird BEC and had to fit relays into the lights so that side lights come on, then go off and stay off when dipped lights come on.....Dipped main go off and stay off when full beam comes on....this reduces the voltage drain effect the lights have on a bike alternator, and never had a problem seeing in the dark because of it. HTH. Quote Link to comment Share on other sites More sharing options...

Crash Override Posted August 18, 2004 Share Posted August 18, 2004 what size battery have you got and did you know that the alternater doesnt charge below 3000rpm.:0 Who are you asking? I have the sealed oddysey battery supplied by westfield, can't remember exact figures for it. Mine charges at idle, just have to look at the stack voltage reader.
