'02 Blade - Turn Turn Turn... Won't Fire?

What revs did you have it at when lights and high beam were on?

IIRC manual says 5k rpm with lights and high beam on should be around 13.5v (not 100% on that dont have access to manual any more)

2002 - aye, it's got HISS. What's the best check then, new battery or new reg/rec first?

gimme 5 mins till i type this up for u lol

Reg/Rec can be expensive m8 so try this first .


CHARGING TEST
Before starting this test warm the engine up to operating temp.

There are several ways of obtaining a reading when checking the charging I will use the simplest one.

Connect the meter and have it set to read volts. Start up the engine and increase the revs to 5,000rpm gradually. Switch on the lights and put Hi beam on.

You should obtain a reading between 13.0v – 15.5v @5,000rpm.

If your reading is outwith the above and your battery is fine and all connectors are clean and tight the most likely culprit is the Reg/Rec.


REGULATOR/RECTIFIER

Before disconnecting the plug on the Reg/Rec check that the Green wire coming out of the harness is attached firmly to the plate with an eyelet connector and isn’t corroded. One of the most “common” causes of charging system failure is this eyelet coming adrift. (This only applies to carbed bikes.)

Disconnect the plug and using the meter check the following terminals.

Terminals Reading check
Red/White (+) and earth(frame-) Battery voltage Batt charge
Green and earth Continuity Earth connection
Yellow and Yellow 0.1-1.0 Ohms Charging coil line

Red/white and Green Battery voltage
Yellow and Green There should be NO continuity.

If these check out then the wiring is fine.

REG/REC TESTING

Remove the unit from the bike. The only way to test is to check the resistance between the terminals of the unit (carbed bikes only).

(+) Red/ Yellow Yellow Yellow Green
(-) White 1 2 3

Red/White ------ INF INF INF INF
Yellow 1 0.5-10 ------ 30-500 30-500 10-200
Yellow 2 0.5-10 30-500 ------ 30-500 10-200
Yellow 3 0.5-10 30-500 30-500 ------ 10-200
Green 1-20 0.5-10 0.5-10 0.5-10 --------
The readings are K Ohms.

If any of the readings are outwith the values then replace the REG/REC.

The final test is that of the Charging Coil or Stator.

This has already been done when checking the REG/REC connector. On carbed bikes the connector is in front of the battery below the fuel tank on the others it is behind the battery above the shock mount.
I can see no reason to check this connection other than to rule out a possible short in the wiring harness from this point to the stator/damaged stator, or to eliminate a short in the wiring from the plug to the Reg plug.

The reading should be 0.1-1.0 Ohms between the yellow to yellow terminals.

You should also check each yellow to earth for continuity.
There should be NO continuity.

It is very rare that a stator should fail. The only reasons I can think of are a wire rubbing through or the bike landing heavily on its left side and damaging the casing and stator inside.

Wow - that's comprehensive, thank you very, very much!!

That voltage coming off your bike is too low whichever way you cut it, at idle even with lights on should never be below 13v on any 12v bike.

Can you turn the light off altogether? if not pull the connector off it, at tickover you have to be seeing at least 14v.

I suspect your charging system tbh not your battery.

Got a m8 who works in Scotspeed m8 if you get really stuck i could make a phone call and see if he can help u out

Not Callum by any chance is it? They're good down there, he's helped me out a couple of times. I actually live 1/2 a mile from Abbey Motorcycles who are also great, so I'll be Ok as far as professional help goes.

I'm a bit of a have-a-go-hero though, so I'll see what I can do myself first then get them to fix it at a much higher cost due to having to fix my mess!

No m8 not Callum LOL ,,, i'm pretty confident it'll be the reg / rec m8 very common issue on blade's and 6er's for that matter ... i'd start searching Fleabay if i were u.

Stick it on charge overnight take charger off in morning then check voltage across terminals. Do the same say after work and see if reading has changed. Idealy be 13.2 v fully charged. If voltage has dropped below 12.3 v over that time battery goosed too.
