If no ammeter, what? #717114

I'm restoring (with a few minor deviations from original) a 1970 A65L. Reading through the forums, I can't recall ANYONE ever having anything nice to say about the stock ammeter other than it's yet another opportunity for an electrical problem. Therefore, I'd like to leave mine off. Is there an attractive way to fill the resultant hole in the headlight shell or is a shell available without the hole? I DO intend to keep my idiot lights. Is a driver available for a low voltage light?

Thanks,

Harvey

I install an ammeter for "looks". Then connect the 2 wires to one stud of the ammeter as a junction block. So it does have some use........

If it doesn't do anything, I see no reason to keep it.

Could be replaced with a blanking plate and an LED voltage indicator, much better to know Volts than amps.

if you have a 70 its an easy task to fit an oil pressure gauge in the ammeter hole ..........i have one on mine but mounted between speedo and taco ..........i would keep the ammeter however they can be made to work.OR..the older ones ex A10 work fine so use one of those

Possibly a fuel tank center grommet (with B.S.A. logo, of course) might fit and fill the hole with a little bit of class and style? Not sure of diameter of the available grommets, though.......

Hardware store also may be a source of a chrome plated cap or plug, often used to fill unwanted holes on electrical items.

If you desire to mount something usable such as a switch, the Lucas 88sa switch for lighting and it's chrome bezel would more than likely fit as well.

Last suggestion: On pre 1967 brit bikes, I solder a flat head screw to an old English half penny or penny, leaving the year side of coin visible. That way I can grunt and point at the coin when they ask, "What year is it?" (Post 1967 brit coins are not as pretty, so I haven't used any of those yet.)

Hi Harvey,

Bear in mind that no-one posts when they don't have a problem ... I have two Triumphs with ammeters and this is the first post I've made about 'em ... wink The only thing I've done to 'em that isn't original is connect a wire between the two terminals; this is based on advice that, if an ammeter goes so wrong it stops conducting, the wire between the terminals will still conduct. bigt

I like something that tells me the electrics are working as they should; so, if not an ammeter, I'd probably fit a Voltmeter.

I'm intrigued by the oil pressure gauge suggestion, as I use 'em, I looked at the possibility of fitting 'em in place of the ammeters but couldn't see the space on either bike (T150 and T100). Plus previous discussions on here about Beesa oil pressures, I'm not sure you'll want to know ... eek

Shell fitted '71-'74 to Triumph T100R's, '73-'74 to T150's and '73-'78 to 750 twins. It has the same 'half egg' shape as the '70 shell but holes for three idiot lamps (oil warning, turn signals and high beam) and toggle lighting switch; if you weren't planning to fit turn signals, the idiot lamp hole could be used for one of the modern LED electrical indicators that change colour depending on the system Volts?

i filled the ammeter hole in my T120 headlamp with a Lucas-copy ammeter from india. not hooked up. cost about five bucks.

looks very nice and causes no problems at all.

Well this is a bit crude, but I'm ok with bodges as long as they're cheap and easy, and not too cruddy looking:

Two stainless steel fender washers, one outside and one inside, held together with a 1/4" stainless steel Phillips-head machine screw and a Nylok nut.

The chrome ring is still there; I guess that's the bezel from an ammeter. Anyway, the outer fender washer fits just inside the raised edge of the chrome ring.

(Hmm, a button-head screw might look even nicer; I hadn't thought of that until just now.)

I exchanged an ammeter with voltmeter and was very happy I did.
Caught my failing battery being in riding distance from home, killed the lights and was able to get there without road assistance.
Having voltmeter you learn very quickly were your proper level of charging should be and every change is very visible.

Adam, can you provide a source reference for the voltmeter?

"I like something that tells me the electrics are working as they should; so, if not an ammeter, I'd probably fit a Voltmeter. The ammeter is a standard automotive 2" diameter, so beware 50 mm. gauges."

Stuart, what does this mean? The ammeter in the headlamp shell is much smaller than 2" hole diameter (~50.8 mm).
Standard automotive gauges (I assume you refer to those fitted in their millions to older cars like the mini) are 54mm hole.
What's the relevance?
Though I do agree a voltmeter (I use a digital one) gives much more info of what is going on in the system. Hth Dave.

what does this mean?

Unfortunately, I'm not near my bikes to be able to check the diameter; attempting to check using the www is inconclusive. frown The rest of the post works without the last quoted sentence so I've deleted it pending being definite.

This is the problem, I bought it as a part of a cheap set of 3 gauges sold for cars in our Canadian Tire store.
The set consist of a voltmeter, oil pressure and water temp gauges. I still have oil pressure gauge, but don't have an original packaging, so don't have any idea where you can buy it in the States. The diameters were right for our ammeter hole and voltmeter proved to be rather sturdier than average ammeter riding in my front lamp for 3 seasons.
I sold the bike last summer with it working flawlessly.
The price for the set was like $30.-
So it had to be Chinese copy of something much more expensive.
