Resistor for making a new loop.
I have to make a new loop.
As the mylaps wire is so expensive I know you can use a thin wire. Does anybody know the value of the resistor that goes in the middle of the loop?
Regards
Dan

MyLaps decoder manual says:-
Check the loop wire by cutting the loop wires from
the connection box and measuring the resistance
between the loop wires in the track. The reading
should be approximately 220 Ohm (for MYLAPS
ProChip decoders) and 470 Ohm (for other types of
decoders). If this is not the case, the loop must be
replaced. When (re)connecting the loopwires to the
connection box please solder with proper connections
(for more information please check your system
installation manual).

However the manual also says this about the entire resistance as messured from the BNC plug that goes into the decoder itself:-
So I would say there's something else in the 'black box' that makes up an entire loop system.
According the to MyLaps website a new set of loop wires is US$50.49.
Check the coaxial cable by measuring the resistance
(with multimeter) between the center pin and the
outside of the BNC connector. The reading should
be approximately 150 kOhm (for MYLAPS ProChip
decoders) and 100 kOhm (for other types of
decoders) after 30 seconds. If not, the coaxial must
be replaced.
