Gauge and wipers issues...

With all the drama I caused with the 318 or slant 6 post I made a few weeks ago...I have decided to keep the 225! Now I have a couple of problems. I think I know the answer but I need HONEST opinions!
1st. I have a 3speed wiper motor, the wipers are very slow to come on, park or change speed, Ground problem, switch or motor?
2nd. The temp and fuel gauge are erratic as heck! Temp gauge sweeps all the time! Fuel gauge is "working" then buried below "E"! I fought this problem only to end up replacing the instrument board due to broken studs. I think the IVR is failing. The temp sender is new and the fuel sender seems to ohm out ok. Be honest and any advice will be a great help! :violent1:

What car are we talking about ?
What charging system components do you have ?
If along with the lazy wipers you also have headlights that change brightness, turn signals that flash at various rates, amp gauge that twitches hard with the signals, your power supply to these components is the issue.
The limiter powering the guages may be bad but...
first things first. Lets first get a good power supply in then see what we get out of it.
