If I have my directional blinking, after about four blinks, instead of one directional light on the tach blinking, both will blink faintly. Does this mean that I need a high output alt? Lemmie know. Thanks!

That sounds like a grounding problem. My car did the same thing, and at the time I thought that was the biggest problem I would have to deal with, but now with all of the crap I had to do on this car, that blinker thing is WAY down the list. But it is indeed a ground issue.

Britt's right. You have some electrical contacts to clean if you want to solve that issue. It's a resistance issue, not an amperage issue.

Dave, I'm glad your unit worked out well. Yours was one of the first shipped out. I think only about half the guys have the cars running with them already. Lots of interest these days.

Group: Members Posts: 4,099 Joined: 21-April 03 From: Gig Harbor, WA Member No.: 598	The only thing I have noticed is when I start the car it must reach about 1500 rpms before the alternator light goes of and I see the Voltage climb on the gauge. I don't remember that from before. At first I thought I might have a belt slipping but, it's fine. After it kicks in it charges fine. Dave

Get that VIN ? Group: Members Posts: 9,312 Joined: 1-May 03 From: Sunset Beach, CA Member No.: 643 Region Association: Southern California	I'm also looking to upgrade due to some of the same reasons, What would an alternator rebuild at a local shop cost compared to Dave's $300 price ?

Bernie Do you think one of these 90 amp alternators would sufficiently supply a high wattage inverter powerful enough to run a small "electric AC" unit--I'm thinking out loud. I wonder if a small unit mounted in the front trunk accessing air like the factory ad-ons and it's output tubed to one of the under the dash bolt on units. What do you think?????

Plus the inverter wastes a lot of power, and the compressor start current is about 4 times the running current. If you want AC get a big engine from Jake and add an original aftermarket kit. You would probably want a new compressor though.

The greater the electical load the more resistance the alternator has to turning and the more it loads the engine. All alternators will drop the idle. It's more noticable with this engine as it doesn't have as much real low end grunt. The stocker held idle better under load. I'm hoping to run an idle air controller with the fuel injection that will essentially crack the throttle minutely when the idle falls. But, that's still in the future. The way it is isn't too bad. I just step the idle up a little and run the idle a little high all the time. Dave
