Bobbin working, indicator green, vest uninflated.

Bobbin not working, indicator red, vest inflated.

Wow...difficult to troubleshoot. OK, canister could have fired and the vest not inflated...but I have never seen that happen."

Over the years, I have experienced a couple of bobbins that hardened with age. The last time at BST, I jumped into the pool with my work coat and stood on the bottom of the pool waiting for it to go off. Finally pulled the manual cord which properly inflated the bladder.

After replacing the bobbin/bottle, jumped in again and it went off immediately. New vs 18 months old.

So, your mileage may vary here, but at least in two cases: Bobbin not working, indicator green, vest uninflated.
