I wish I had an exact answer to the high RPM light problem.I've seen it on a lot of units,not just mine.I've been thinking it over for quite some time, and have come up with an idea.:idea:
Stock units use 25amp soldered button diodes.
The rectifiers I've been using have spot welded avalanche 50amp press fit can diodes.Very heavy duty.
All diodes leak at a certain amperage,hence the rating. With the 200amp stators i'm using (I call them 160amp but they are marketed as 200amp) I'm thinking POSSIBLY they are leaking at full output , which could trigger the light.
I can't prove it on the bench,it's just a thought at this point.
So I found a place that makes a 70amp diode version rectifier,I have 3 on order & will get those built,first one will be to replace yours & see if my theory is correct.
It's just strange how this only happens on a small number of units I sell.It's only the 03-04 Cobras,the V6 GT's work just fine,same alternator besides the pulley.But I do see it as a problem & am looking to eliminate it for once & for all.
SLightly off topic but i figured you boys might know. My 5.4L turbo car has been having a mess of issues this year. My car is going badly lean at WOT and i couldnt figure it out. Changed pumps no better, battery is brand new ( Red top ) so the other day driving it home. ABS light starts blinking ... sitting at a light sterio dies.... im like awww ****. rev the car up all is good. Limp it home and leave it. Go back 2 days later fires right up ( had a loose batter connection ) figured great fixed it. Take it our for a drive about 5 blocks from home Light starts blinking. No battery light just ABS> can i assume that my 01 cobra alt is DOA and needs to be replaced ? Im hoping this also fixes my lean fuel issue as the pumps are direct wire off the battery. Thoughts ? I have trunk mount battery with 0 Gauge welding cable power to my kill switch off the power post. Grounded to chases in the truck. Doubt my switch is the problem at this point
