Programming jumpers
4103XV
R
➢
Light flash (+)/(-)
This jumper is used to determine the light flash output polarity. In the (+)
position, the on-board relay is enabled and the unit will output (+)12V
on the WHITE wire, H1/9. In the (-) position, the on-board relay is dis-
abled. The WHITE wire, H1/9, will supply a 200mA (-) output suitable
for driving factory parking light relays.
Note:
For parking light circuits that draw 10 amps or more, the internal
jumper must be switched to a (-) light flash output.
P/N 8617
or a
standard automotive SPDT relay must be used on the H1/9 light flash
output harness wire.
➢
Tach threshold on/off
In most cases, this jumper can be left in the OFF po si tion. Some new
vehicles use less than 12 volts in their ignition systems. The unit may
have trouble learning the tach signal in these ve hi cles. Changing the
jumper to the ON setting changes the trigger threshold of the digital
tach circuit so it will work properly with these vehicles.
