Programming jumpers

513

➤ Tach threshold On/Off

In most cases, this jumper can be left in the Off position. Some new vehicles use
less than 12 volts in their ignition systems. The unit may have trouble learning the
tach signal in these vehicles. Changing the jumper to the On setting changes
the trigger threshold of the digital tach circuit so that it will work with these type
vehicles.

➤Light flash (+) / (-) polarity

This jumper is used to determine the light flash output. In the (+) position, the
onboard relay is enabled and the unit outputs (+)12V on the white H1/11 wire.
In the (-) position, the onboard relay is disabled and the white H1/11 supplies
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 H1/11 light flash output harness wire.
