first,
i read what carl posted and that answered my question thanx farmer brown!!!
second
i don't really like transponders on vintage karts.
numbers are the classic but numbers require talented track people capable of accurately recording the results.
people = money expense and it seems a whole lotta tracks are using transponders instead which give accurate results without a lotta expenses.of course i also have noticed that many traCKS NOW RENT THE TRANSPONDERS TO DRIVERS FOR A LITTLE EXTRA.
apparently they don't think saving the costs of paying four to six track gals recording results was enough.
i enduro racing you have to have one and i'm gearing up to roll either the margay or bug next year .
i always like long track enduros and now with me not promoting i'll have time again.
so i needed at least one for that.
with that in mind i came across one complete in box at a swap meet and convinced the owner that they were obsolete and maybe being phased out.
i had seen the new subscription style transponders so i was sorta honest.
i was hopeful i was wrong about them being phased out and it seems i was which is good.
the other one i got when i specifically bought a kart for the transponder and and a few loose parts.
i resold the kart at cost plus maybe 20 bux.
so now i have two even though i'm pretty clueless about them.
they both hold charge so i might as well use them at the tracks requiring them for place scoring or what ever.
also
if anyone has one with a dead battery there is a service now that will cut the old battery out install a new one and reseal the unit.
