One of my 90's is have these symptoms and I was wondering if this is happening to any others......

When I put the wipers on delay, every time they cycle on, the tach goes to 0....:confused:

When the wipers go to park position, the tach comes back on and registers the correct RPMs.....

I am leaning toward a bad ignition switch....

The alt / battery light occasionally comes on as well even though I have had the alt checked and it is putting out the correct voltage.....:rolleyes:
 
That used to happen to my 89 then the battery went bad. Free replacement from Autozone and hasn’t happened for the last 2 years.
