Fuel Pump power dropping out

Postby RoyH on Sun Jun 18, 2017 1:02 pm

I have an EnerMatic Controller running an Ample Power 150 amp 24v generator.
It worked fine for a year or two with the occasional cpu freeze.(I never bothered to set up a watch dog timer)
Now the fuel pump will not stay running. It shuts off after running a few seconds or runs and shuts of when the engine cranks.
It's connected to the FUEL terminal on the EnerMatic. I've tightened the terminal and checked the voltage at the terminal while attempting to run the engine and it drops out intermittently.
The pump is the pulse type sold by Ample Power.
Any suggestions for where to look to solve my problem? I would appreciate any advice.

How is your 12V battery? Few years old? Does the pump work fine till the engine starts cranking? Maybe during the cranking the 12V drops to far?

Just some thoughts.
