Hi Rex/LAB yes still have a -4amp reading when engine is revved needle does not move at - 4 with no fluctuation

originally I did have the reg/rec neg wire straight to the battery terminal with red to earth (as per Lucas diagram)

I then ran the rec/reg neg wire straight to the ignition side of the ammeter with the brown/white wire this made no difference to my

 situation still reading - 4 amp even with engine running or not

I have noticed with engine running if I use the rear brake the  stop light comes on with the ammeter moving very slightly to neg while

 the pedal is depressed when released the ammeter returns back to 0 ?

still looking into an an acetylene conversion just waiting for technical help from the V & A museum

Hi Rex with engine running with main/dip on when  revved the ammeter just stays at -4 till I switch to pilot then the ammeter stays at 0
 
and does not move even when revved  at this time I am still getting a 14+ volts reading across the battery terminals ?

I'm still a bit lost

Hi John thanks for the reply I have tried swapping round the ammeter terminals and yes I then get a reading of + charge ( engine off)

still a bit" lost"  on this problem, here in North Wales we still have travel restrictions so I have not yet had the bike on a decent run

to see if my - 4 amp reading on the ammeter changes at all

I will do your suggested battery run down today and post my findings

thanks for the reply Mark I'm going to get another ammeter although this one is new it is a pattern part so I  will replace with a genuine

item if only to eliminate a possible dud unit.

I had all afternoon on the elecs. yesterday I ran the black neg wire (from reg/rec) to the ammeter brow/white side

 and still have the same problem tried it on the other ammeter terminal terminal no different

still getting 14+ on the battery terminals when revved

 although I have noticed when revved the ammeter stays at 0 it does not move at all ?

I have boyer ign fitted which has been fine for 1 year, with the new loom I have the points/condenser/diode/rec wires

these I have just insulated for now

ammeter is a new pattern item just wondering could this be giving an incorrect reading ?

also contacted the V & A museum regarding acetylene lamp details !    any input gratefully received

thank you LAB your input is much appreciated

 I will re run the reg/rec wire to the ign side of the ammeter and hop fully resolve this situation and post my findings 
 
PS I did receive this advice from another site just now sure describes my electronics skills

Hi LAB thanks for the reply I may have fkd up here (bike is + earth) as I have only 2 wires going from the new loom to the ammeter

brown/white & brown/blue no other wires at all

 I installed  the new Lucas single phase 120 watt reg/rec as per the instructions ie: discard original diode & rectifier

 connect  2 x yellow wire from the stator then a black neg to the battery ( new reg/rec has 4 wires only 2 yellow 1 black 1 red )
 
and a red pos to earth/ground so do I still need a wire from the ign. switch to one side of the ammeter ?

I am the first to admit I did not take my apprentice in quantum electronics for the Hadron collider

I have just been puzzled as to why everything works apart from the neg. amps on main/dip

I will investigate further tomorrow and post my findings

Hi John yes when revving the engine I get 14+ volts across the terminals with 12 + on tickover

I have a new Lucas loom installed the only wires going to the ammeter are from the loom brown/white & brown/blue

my rectifier is a new Lucas single phase 120 watt unit with a Lucas 47205 stator

so I will have another go today and post "any progress"

I am using a brand new battery (12v 5ah 80A)
 it is fully charged so I assume it will not take any more amps
 as before the needle reads 0 until I switch to main/dip then reads -4ah  , had another look this afternoon and "am still in the dark" ?

Hi rex thanks for your reply when revved with main/dip selected the ammeter  stays at -4 amps
 with 14 v + reading from the battery
on pilot lamp the ammeter reads 0 volts so I am assuming charging/ammeter are correct ?

Hi Iansoady thanks for the reply
 I realize the colours will bear no relationship to the original set up just very puzzled why I get a -4  drain on dip and main when pilot responds normally
I will continue with all combinations using my multimeter and post my findings.

I hope someone can guide me finally got round to replacing the handlebar dip/main/horn switch

the new one has 4 X wire yellow/green/black/white,  black works the horn

I have tried all combinations for the other 3 wires and have got the pilot/dip/main working from the switch

on pilot headlamp switch to middle all is good when I switch to main/dip the ammeter reads -4 this happens with engine running or not
 
I have a good charge to battery 14v + new Lucas single phase 120 w reg Lucas 47205 stator & new rotor
rear/stop lamp work fine,

4 wires to connect up what could go wrong ? where have I failed ? help !

I use a Wassel set up on my TR 250 W very straightforward to install easy starting £60 all in.

Hi all after pouring 200ml of oil down the inlet rocker and leaving it overnight I gave a few slow kicks ign. off then started the engine and was very happy to see a healthy return flow to the tank
 I guess when I initially drained the running in oil overnight there was none left for the scavenge pipe to pick up ?
however thank you all for your input "relieved" of Criccieth

Hi Rex I have had the motor running and barely get a weak dribble back to the tank even if I rev it a bit
so last night I poured 200ml down the inlet rocker hoping this will drain to the sump and the scavenge pipe can pick up
I will post my findings
am I correct in filling the tank with 2.83 (5 pints) litres of oil ?
