Lucas ammeter

Forums

following a short and heavy discharge my ammeter needle assembly has bent. . Has anyone dissmantled one ,  before i cut it appart !!

It's unlikely an old Norton Motorcycle still sports its original ammeter. I am inclined to think you'll find it unrepairable, in view of the cost of replacement I'd get onto RGM and buy another.

Hi Graham ,  It is an orrig 1960 Lucas and a bit rusty  but  it  suits the rest of the bike ! ,I have another orrig that I found in the woods ! ,may be good for bits.  The "NEW"  ones are  indian made and have silly  tiny  connectors  (I have one)  and are reputed to "waggle" all the time. I would much prefer an orrig .  I bought a new  "Lucas" rear light  that  finished in the bin in 5 minuits ,I then  glued the orrig back  together  that was 10 years ago and its still fine. I do buy new stuff , but it usually finishes up " for display only" in the junk box.

Is usually getting inside. Older ones were screw on later that were crimped on as I remember.   If you can get the bezel off the instrument is a very simple coil and armature device. If it’s just damaged by a high discharge which drove the needle into the stop post and still works then it is a snipe nose pliers job to straighten the needle.  If the coil has burnt and it is not registering, take the guts out of a replacement cheap unit. Probably be able to swap the needle for the right look.

I’ve worked on a few, if you want me to take a look. PM me…

Why not put the ammeter across a battery to bend the pointer the other way? Be quick!

I have eaten my words Robert!! I have wrongly assumed that you're dealing with a different ammeter than the one the bike left the factory with. As someone has pointed out the pattern ones are not the best. So yes I see your quandary, if you don't decide to have a go yourself then here is another option for you- (guagerepairs.com). The proprietor {Peter Bond} specialises in motorcycle clocks so I'm wondering if he can help you as well. If you want the gauge to work properly again it might be worth paying a specialist?
