Hi there,

I purchased a D jet kit a few years back thinking convert my dual carb back to fuel injection.

I begin to inspect the parts I received.
First the MPS.
1. Pressure is good holding at 15 PSI
2. Outer Terminal(7, 15) : 94
3. Inner Terminal(8, 10) : "OL".

What does the outer and inner terminal control ?
Can it be fix ?

Tks.

15 PSI is probably OK if it remains steady. A steady 18 PSI is recommended.

The inner two and outer two terminals are contacts for the two coils. You should see a resistance between the outer two terminals of around ~350 ohms. If not, the problem could simply be a bad internal coil connection or the coil may be defective. The back half of the MPS can be exchanged with a known good part, requires disassembly. I may have one to swap, but you will need to send me the MPS for the repair or swap.
