Typical Readings

The primary readings listed below are for your convenience, and are the result of our own

Field Testing. Variations of ±10% should be considered normal. We strongly suggest you

test some known good vehicles to get a feel for the readings. Refer to previous page for

Starting/Charging and Power test readings, which are the same for DIS and Distributor

engines.

Exhaust KV Less than 4 KV. If higher, check for wide gap or broken sparkwire,

or fouled plug on opposite side.

Burn Time Uniform among cylinders If shorter, check for breaks in secondary wires,

If longer, check for fouled gaps or insulation

shorts.
