On the optima, I have experienced rebooting with the primary many times. It only does it underwater. I have tried every possible way to adjust the po2 (run up manually, etc) to avoid the solenoid firing on restart, but nothing works. The battery is fine on the primary and secondary, I verify voltage using a multimeter both before and after the dive, I am using the 3.6V saft batteries as recommended by dive rite. Any ideas why the primary keeps doing this, there should be no reason for this with good battery power...am I correct?

Have you tried burring the threads so they bite into the casing? Also conductive grease. Take the spring out and clean it. Clean the inside of the battery cap. Put grease around the base of the spring and reinsert into the cap.

Burr the threads on the cap or put flats on them by supporting the inside and using a hammer and dowel to flat spot the threads.

Finally I clean the contacts on the batteries before use and i use a smear of silver grease on each end.

So far so good.
