Wat r e sympthoms if rectifier not working?

 

Batt not charging

[tanhjsg]

Thanks. I heard that can actually do a bypass to make the fan continuously run, is it recommended to do so? what's the estimated cost if i send my bike to do up the overheating problem...sorry, still new and i dun wish to be ripped off by bikeshop. Appreciate if someone can let me know so that i can go ATM and press enough money.

 

 

The reason is heat cannot be dissipate fast enough... Resulting in pressure build up and boil temp and flow out..... I would say faster check ur coolant level and go to a bikeshop unless u know how to DIY because ur

 

Ur radiator system dirty Liao..... If flushing can solve then small prob.... Orelse nid through clean the radiator:)

Batt not charging

 

Hi lxy, I know that we can't trust e batt volt meter much. But now when I'm traveling it reads abt 11.8 to 12.4. Happens these two days. Wonder if it's e volt meter spoil le. Cos I just replaced coil batt rect. That day I told my bike shop e rect cost $65 they were shock as y so cheap. Then told me mine is small one from china. Told me original is $220 big one. Is it true?

there is no harm to run the fan continuously...they just help u put a swtich or when u ignite auto on.....but seriously i don see the point cox it onli solve ur overheating prob on the surface...

 

the real problem still lies inside the radiator system...maybe alot of rust or something resulting to your overheat....

 

my guess is doing wiring cost u about 30 bucks..... by adding maybe say additional 20 -30 bucks...u can go to your mech to rectify the prob...if nid flushing...for wat i know unique cost 50 including engine ice... while if hose problem or wat..other prob...it maybe more expensive...but at least u know problem is solve:)

 

just my advice:)

RECTIFIER got big or small one meh? hehe

voltmeter is not as accurate as u measure directly to the battery.

just 2 cents:)

[cwmike21]

Rectifier got big and small. Was told by racewerks mech that big is modified de. Anyway volt meter is always used as a gauge. E reading shown diff a bit. But mine old one spoil le. Read 11.7-11.9. Scare me out. After changing e volt meter is 12.6-13.1 le. Hee

Need some help here. Any recommendations for battery?

I'm riding a spec3 and the batt I'm using now is some

cheap Korea brand batt(can't recall the brand name) which

was given to me by the bike shop when I bought my bike.

I was told the batt is not suitable for vtec models.

Rubbish lah. Try using ur choke next time. When using choke.don't turn throttle initially.

No..its on your left side back panel where the fuse is. Look for a red connector..pull it off and there is a green 30 amps fuse. Just check the 4 pin or so connector that they are not rusted badly.

[Blassreiter]

I thought all crash bars are mounted to the frame? Anyway I think almost all bike shop have lah

The red connector has a locking "catch" on each side..u hve to squeeze the upper end to unlatch and pull..its tight and have to shake at the same time. Many has done it..u have to try again.
