Road Racing - Anyone have an AMB rechargable transponder ?

Odd ?, I have managed to misplace my trasponder charger.
Can any one tell me what pin is 12V+ on the charger?
Thanks.

I'll take a look in a few...not sure if it tells you though

Aren't RC car transponders 8V?

Thanks!
I am 99% sure it is 12V. The charger was a cig. lighter and went straight to the box.. there was nothing inline to offer a voltage drop.

SIK02SS you can use a DVOM to find the polarity. Plug it in, hook up the leads on the DVOM to the contacts on the base charger then switch them. Whatever way the display reads pos (or not a neg number) will show you the B+ contact. (the b+ contact is the one that the red lead is on when not showing a neg number)
I just need to know if the one closest to the end or center is the pos.

Thanks in advance!

Not a RC car transponder. I have had this one for 10 maybe 15 years! I know all you guys prob. run hard wire ones now. i'm just to cheap to upgrade.

Forgot to look on my lunch, sorry. I have to get back into the trailer again tomorrow...i'll make a reminder for myself. And noted. I'll check it.

No worries, Not running till March.
I do appreciate your help.

Went to your website, great looking car!

Thanks! Couldn't find my voltmeter until i was leaving the house back to work..so check back again later tonight :lol:

The one closest to the end is POS :)
