Solenoids failing -mzj-400

Did You try powering them up again?

I have mine mounted horizontally as well as it provides a more "neutral" position for the plunger and springs.

A fly-back diode is also critical on that two coil design as it not only provides protection to the switching device but it also reduces the L2 coil discharge current when the N.C. contacts return to their normal position.

Not yet. We flooded pretty bad on Monday. Had the cart in parking garage but been dealing with all my other stuff. I will try to power them up next week and see if they work. Might try changing solenoid mounting position also

Here is picture of current mounting position. Am I understanding it correctly that Rotating 90* Would be a better position?

[Sergio]

Yes and it looks like you have plenty of room to have it sideways (coil barrel in a horizontal position).

On my build I used the unused space behind the battery bucket to allow room for the "bottom" of the Solenoid:

The XCT should not have a pre-charge resistor and it needs a Regen diode (10A10 diode) with the "Stripe" on the post that has the pack positive cable.

I am glad you posted that picture bc I wouldn’t have mounted it correctly. I was going to mount it sideways.

[Sergio]

If by sideways you mean one big post UP and one DOWN, that is correct as well.

The "Horizontal Mounting" refers to the orientation of the "Coil Barrel/Cylinder".

You can achieve that orientation by Wall Mounting or Floor/Ceiling mounting the Solenoid.

Remember to remove the pre-charge resistor and add the Regen diode.

It would be a good idea to also test that fly-back diode to make sure it is good.

thanks will give it a try.

Can you clarify removing the pre-charge resistor and adding regen diode?

I am pretty sure i Have the pre-charge installed on my large terminals and the fly back diode is installed on my small terminals. are you saying to remove the resistor off my large terminals?

[Sergio]

Look at notes #4 AND #5, You need to remove the pre-charge resistor and install the "Regen Diode" on the big posts with the stripped end of the diode on the post that has the pack positive cable.

Thanks, guess i missed that part when I did the install.

I will order a 6a6 diode.

Would a 10A10 work? I have some of those on hand.

[Sergio]

Yes, the 10A10 is even better
