Autometer gage problem

I have a 6 gage set of Artic White Autometer gages in my Willys. I also have a 100 amp one wire alternator. All of the gages work properly...

Except when I first start the car cold. The gages all seem to be active when I turn the key on but when I start the motor it take a full minute for them to begin reading. I tried to reve the motor over 1500 rpm to "latch" the alternator which seem to work when hot starting for the voltmeter.

Once the gages are reading they are fine. I can shut the motor off for a good half hour and restart and the gages work right away. It is just the cold start the seems to be the problem. It's almost like they are on a timer.

I checked the alt belt and it is tight, no fuses blown, no chinzy wire anywhere on this install.

I have a Painless wire harness, Summit ignition box, brand new big battery and good solid clamps. The car is a "plastic" car and has several ground strips throughout it. I'm a 'ground' fanatic.

The motor and frame are grounded in 2 places each to the battery with #2 welding cable with good solid connectors and star washers.

Anybody else run into this.???

I do not believe that your one wire alternator is causing the problem. Does your speedo swing full scale when first applying power?

Yes it swings around and the odometer reads about 11 then it settles down. It has not been calibrated yet as I haven't been able to drive the car around except in the parking lot. Autometer said it will have some feed back untill it is calibrated the first time.

thanks for the MAD link.
MAD presents a strong case for the 3 wire alternator. I got the 1 wire about 6 yr ago at the start of the project. Even before I had the wire harness. With the downturn in the economy I have to pull in the horns and use what I have for now.

As I wired the car I thought about the replacement issue and I left the additional wires and connector in the harness. It would be possible to replace the 1 wire with a 3 wire at road side without too much trouble. When the 1 wire becomes a problem or I add some high powered devices I'll have to replace it but for now it will stay. I only have halogen headlights, electric fan and MSD/Summit ignition that draw significant power. I'm not a highpowered stereo fan so that is not an issue at all. It would be nice to have my 12v coffee maker but I already have found that even my diesel truck doesn't like a 25 amp draw thru the power socket so I'll have to stay with gas station rotgut coffee. haha.

I do have a huge power wire from the alt. I think it is a 6 ga if I remember right.

Last night we moved the car to another garage. I had fully charged the battery right before we moved it and the problem still showed up. As soon as the car warms up or has been run a bit it goes away. Maybe there is some magnetic feature that happens and hangs on for a while. It was about 60 degrees when I first got the car running and it didn't happen then even though the battery was down a bit from working with the headlights. It started when it got really cold recently...20's. By the way this hotrod motor even with an air gap manifold and hot cam starts really nice when ice cold. Typical of carbs when cold, pump the gas twice and crank. Starts everytime.
