Just installed a new Autometer Ultra Lite cluster from Covan's Classics, everything went well except now my turn signals are slow and even slower when the headlights are on.
Any suggestions?

 

How do you have them connected?

 

Just as the install manual said, eveything plugs into the factory loom.
Problem is worse than I thought, just took her out for a spin around the block and it looks like I'm running off my battery, the voltmeter shows 10 - 11 volts, everything losing power, stereo barely works...
This HAS to be something I've stupidly overlooked because the car ran great with the original cluster.

 

did that cluster put a resister into the brown wire to the alt?

if not, it won't charge

 

No mention of a resistor anywhere in the literature.
The only brown wires I found were for the cruise control and went to the ecm.
Its a 1988 IROC 305 4spd. auto

 

well, you need to put a 100 ohm resister between the brown wire to the alt and key on power

I'll see if I can find a diagram for you
