To positively determine if the problem lies with the operating system or the unit itself it's best to run it with the gearbox cover off and operate the checking lever. </div>

<div dir="ltr" data-setdir="false"><span style="font-size:13px">Doesn't sound like the pump - 400 psi is good, but this can be removed/resealed in situ.</span></div>

<div dir="ltr" data-setdir="false"><span style="font-size:13px">I had a solenoid that was 'weak' and behaved like yours. It functioned, but resistance was high and pull force was low.</span></div>
<div dir="ltr" data-setdir="false"><span style="font-size:13px">It might throw but have marginal force to open the ball valve when under pressure.</span></div>

<div dir="ltr" data-setdir="false"><span style="font-size:13px">Best way to isolate this is to check resistance or current of the solenoid.</span></div>

<div dir="ltr">I've had an intermittent issue with my BJ8 O/D. It doesn't engage <br>
</div>
<div dir="ltr">reliably, but does maybe 1 out of 10 attempts. I think I've ruled out

</div>
<div dir="ltr">electrical issues, as the solenoid activates reliably. I checked the
