Re: Smart injection
The relay should not have any problems, we have been using them for 16 months, not one report.
You could be right, since you are taking barely any flow so pressure stayed pretty high, hence the current. Half a turn counter clockwise will reduce it by ~15-20psi.
I am sending you a unfused 40A relay + an inline fuse. In case the other two failed again. Do you mind send the two relays back to me for examination. I will not charge you for the replacement. I will also send to a suppression diode to minimise arcing.
