Hi all,
Nice to see Barry Q's post about his Bullet enjoyment!
Meanwhile I still have not properly sorted my charging problems from a couple of months ago.
I have tested the alternator output and all seems ok, now I am diving into the un-chartered (for me anyway) waters of reg/rec diagnosis... As you may remember I have 2 sets of reg/recs as the previous owner had re-wired the whole system... I have now been given a spare reg/rec (2 units) to see if I can isolate where the problem is. Apart from mucking about with bullet connectors this should be quite straightforward... but is there anyway of testing individual units to see if they are obviously knackered? The regulator I have already removed has 2 pairs of wires leading to a single connector - pic is here (have removed the connector to use it on another unit)

The unit I swapped over has made no difference, bike runs ok with lights off but after a few minutes with lights on the battery runs flat, and I get a minus 2 deflection on the ammeter.
Is there a test I can perform on the reg or the rec using a multimeter?
The other question is has anyone ever bought these Swiss units?

At that price it may be worth a go? The other thing I'm wondering is if one combined unit will be enough... someone out there may have gone through this already?

hi peter,why not try a new rectifier /regulator ,our host sells the power box type or you could buy a single phase wassel type ,these swiss rect/regs are terrible ,i saw one fail quite recently on a pals bullet,no charge no lights etc i fitted him a suzuki item i had laying around charge returned no drained battery since ,atb paul.

Thanks for the heads up Grunda, I know you get what you pay for... just wanted to get myself out of trouble as London tube fares are killing me and I need to get to work and back!

Hello there PETER 53, ----- Is this Enfield your only means of transport then ?? Why not buy a cheapie "commuter 125" say a Honda CG125 for example---- to off-set the Bullet's downtime.

Hello again matey !! Would you mind if I offer a bit of constructive advice ?? Re}--- those soldered joints. Rather than have them side-by-side as shown, make them staggered. That way you avoid an unsightly "Bulge" in the finished loom....And heat-shrink over both individually then over the combined assy. for a nice, professional appearance.......Alas, can't help with the electronics as + and - is my limit !!!LoL

Peter,
I know we have been over this before but with a new single rec/reg unit it is simple to wire, red positive, black negative and the other 2 wires to the alternator. I know your wires aren't coloured correctly but by wiring it this way at least you will charge the battery to get to and from work even as a temp fix. I assume you have a 3 wire alternator fitted. If 4 wire this may be the reason 2 rec/reg units have been fitted

Alan,
I sold my beloved Z200 a couple of years ago (so we could afford school uniforms for the girls) so alas the Enfield is my only bike... I have had good news on the cash front (early xmas present) so will be ordering a power box... just need to sort out which one as I have a 4 wire alternator.



Thanks for the soldering advice! This was one of the original regulators that I cut the connector off to test the one I was given, by no means finished yet, just a quick job at work while I had a minute.

Norm, yes we haave been through this before but thanks for your input once again... can I use any of the power boxes with my 4 wire set-up?

Otherwise I will get one of those cheap units and see if that will get me out of trouble for now.
Cheers
Peter.

Hi Peter,
I think this stator is from a Lightning because of the wire colours. Firstly do you know the stator is charging?I'm not sure what A/C voltage you should get from each set of coils, if somebody knows this I'm interested. You should get around 30 volts A/C from a 3 wire with the coils combined but I'm not sure what a 4 wire should produce. Anyway if your stator is working and you were going for the powerbox the 2 BL from existing rec/reg units need to be combined and go to the black on the powerbox The 2 BR combine and go to the red from the powerbox. Then a PU combines with a P and the same with the other PU and P. Run the motor and take a reading at the battery and see what volts it is getting. Reverse the Pu and P wires and take another reading and then use the combination which has the higher reading. I think this is how it should work but I would like to know the stator was working first

Hi Norm
Thanks for staying interested! I did test the coils a while back and got something over 30v from each one, so that led me to believe that the fault lies somewhere after that. Now this is where it gets confusing, as I was sold the bike as a 1999 535 Lightning, only to find out later that it is actually a 500, due to the bore being 84mm rather than 87mm. But it could still be a Lightning 500? The Enfield Owners Club gentleman told me it was a standard Bullet when I gave him frame and engine numbers during registration process, but I need to check with the previous owner if he has changed the stock alternator or this is how it came to him.
I have a sneaking suspicion that it may not be possible to use a powerbox, but will check with our hosts tomorrow.
Cheers,
Peter.
