is it my reg/rec or altenator???

[rswspeed1]

checked the voltage on baterry and its 10.6v when i rev it the voltage drops and if i switch the lights on it cuts out.
and also i disconnected the reg connection and the plasctic around one of the pins is burnt
is the reg/rec faulty??
thanks in advance

I would say so. Sounds like it's probably killed the battery too. Safer to replace both reg/ rec and battery. (I replaced all 3 a little while ago, battery, reg/rec/ and alternator for the same reason.)

thanks for that, i bought a new battery 2wks ago still in its box so just need to get the reg/rec,
i took it down the road for for a spin (about 5-6 miles) and it was overheating could this problem be connected to the reg/rec at all?
thanks

I wouldn't have though so. Overheating due to lack of cooling through the rads, best have a look at those too, they can get rather blocked especially the lower one if not kept clear.
Check it's got some anti-freeze in it, sounds daft but if someone has just been topping up with water the anti-freeze might be very low. 5-6 miles does seem rather quick to me. Do you mean it's up to temp, 90 degrees or so, or way up high on the gauge?

i just switched the bike off and noticed it was boiling/bubbling/rumbling. but it has been stood for about 2 months previous to that 'spin' down the road.
ive seen a thread about cleaning the system on here somewhere so ill start searching

On that not - water is a better coolant than antifreeze anyways...so more water = better cooling..

Really?! Well you learn something new every day!

But on another "on that note" if you do just use water it will rust the crap out of the impeller in the water pump so unless you're racing and drain the system regularly it's probably best to use anti-freeze.

[CMSMJ1]

Oh yes...I drain my water out every month or so...and I add a dash of antifreeze too..but more like 10%than 50%..

I like pretty colours in my coolant bottle

loving the baps

i put the other rec/reg on and started the bike and i was getting 13.8v switched on the lights and it dropped to 11.2v, i then switched them off and it remained at 11.2!!!!!!!
also these readings are with the battery that i think needs replacing (new battery currently on charge). would a crappy battery make a difference to the readings???
thanks
