Aerator auto manual switch

[Trapper54]

I recently purchased a 1989 tracker pro 17. The aerator works on manual but when switched to auto nothing ever happens.

I don’t see anything that might be a timer anywhere, could timer be part of rocker switch?
Where can I find a new switch any help would be appreciated. Thanks

Look at pinehawker's post and the pic of his fuse block..the timer is the red round component with wires coming out of it.. next to fuse block.

Here is wiring diagram for 1990 should be close..Timer is not part of switch, any DPDT switch will work that fits. Something like this here:

Rigrite 520 is probably the timer. Wiring schematic is at address below.
