Re: Smart injection
The pump should only come on when the system is about to inject. Have you altered any jumper links or set the threshold trimmer?
The pump pressure can be adjusted via a 1/16" allen key at the front of the pump. Factory setting is 160 PSI at deadhead. The ticking sound is quite common on this type of pump. It has an radial offset cam. May be there are still some air in the pump head.
The pump draws about 7-8A at 160psi. 11A at 220 psi. In order to lower the current, you can reduce the pressure down by 1/2T. As you are only use a very small amount of water, you can run lower pressure and reduce the temperature.
More importantly. The pump should not stay on. Relay draws about 100mA , it does get warm over time, but not overly so.
Let me know if the system turns only with the key in the "pre-crank"key position and not
before.
