[Pump Only Primes With Main Drain, Not Skimmer]

put more water in pool, until the skimmer works right.

[Jandy 400 Lx Heater]

The heater would not light. No power to the ignitor. I put an ignitor controller in. Has power to the ignitor. Check voltage to ignitor, and only 50 volts. Not hot enough to fire. Need some input.
