when you say "check all the wiring voltage drops" what does that mean to someone who has never touched wiring before?

Thanks
With it all connected up see if the outputs from the reg-rec are losing your charge.

I.E set meter to DC-V and put on contact in the back of the regreg connector on the live, other one to the battery live. If there is a big voltage drop here you have a high resistance which is losing your volts for you.

ok - so the results from some of the tests.

YC - your voltage drop question above, I get 0.13 volts at idle (not sure if that's good or bad) - should I try it at revs and with the lights on?

Next test - Alternator output, on all three yellow wires it was reading 85volts at 5k rpm so I think that's good. Also with engine off the resistance read at 1 ohm for all wires

Doing a diode test of black and red to the three yellow wires on the RR, they all read ones?

So where does that leave me? (apart from with a multi meter and an RR on my lap typing this?

0.13V is ok ... if it is like 2 or 3 volts you have a big problem there because you are losing a lot of power somewhere.

(P = IV so if your bike is drawing 20A then you are losing 40-60W of power, this will show as a very hot connector or wire somewhere)

mmm - hunt for a hot wire time. Does the RR sound ok then?

Re: Regulator chat thread.
 
Sounds like a reg rec fault because:

a) you just checked for a power loss across the reg-to-battery wiring and found it within reasonable limits
b) you just checked the alternators output and found it to be healthy

So you are putting power into the regrec and it ain't coming out.

cool - ok well I got bored and had a hunt round a couple of local breakers and no joy on the later models so off to fleebay to have a look it is.

mmm 18 quid that sounds like a very good price m8, is 35 quid a reasonable price for one of these or way over? Someone a work has one for 35 so may go for it?

lol how popular is reg/rec failure lately. I've been informed my FH008 is on its way hopefully have the curvy up and running shortly.

Must be the weather, lets just say I have plans of greatness for my knackered one ;-)
