Slow Blinkers need help!

I think the blinker can uses heat to cycle a relay in there, like it heats up a spring or something, on the lines of a mechanical voltage regulator.. PErhaps the draw is too much for the thing to work? I recall a blown blinker will cause the good one on that side to blink very fast....just theory here. They are cheap anyway.

Bi metal strip heats and causes the two metals to expand at different rates causing it to bend and make a set of points open and close.
So yea, that's about it.

The electronic style uses no moving or heating parts, just a timed electronic switch that load does not affect.
These are great, because it does'nt matter how many lights or what the amp load is.
They will also flash the same speed even at idle when the old style slow down.
