You really seemed to answer your own question. 2 transponders in the same car with the same trouble, i'd bet it isn't the transponders. Try the 2 you have in another car before you go thru the trouble of rewiring stuff.
NCFRC said:We've run across this with two different AMB personal transponders.
They will miss 3-4 laps in a 50 lap event ?????
Mounted on a fibreglass pan chassis with a square hole cut it chassis so the transponder has a clear view of the track.
Wire under carpet so the distance is less than 1/2 inch above loop.
4 cell car and have tryed in two different reciever ports.
After buying second one seemed to fix problem for a few weeks, now back again ,,,,,hate to buy a 3rd.
Havn't sent back to AMB yet.
Thanks for any input :thumbsup:
