New Kirban 200 amp alternator reading 15 plus volts on scan master.

[LEGACY_GN]

Is this bad, normal or what?

 

[RIFF RAFF]

YOUR OK . IT HAS TO CREATE MORE VOLTAGE , SO IT CAN KEEP THE BATTERY CHARGE UNDER A LOAD .

 

[LEGACY_GN]

The old alternator never got above 14.1 and a guy in houston said he thinks thats way too much and will burn things up. He said the voltage regulator must be bad?

 

[RIFF RAFF]

WELL BY ALL MEANS GO WITH THE GUY FROM HOUSTON ! I GUESS IVE BEEN BURNING MY STUFF UP FOR YEARS .

Does your scanmaster show volts in the mid 15's?

 

[RIFF RAFF]

YES ... MY SCANMASTER READS MID 15 TO 14 MOST OF THE TIME .. THE SCANMASTER SEE'S ECM VOLTAGE NOT BATTERY OR ALT .. 4 VOLTS OVER 12 IS WHAT MOST GOOD BATTERY'S READ OFF THE SHELF .

 

[BobbyBuick]

YES ... MY SCANMASTER READS MID 15 TO 14 MOST OF THE TIME .. THE SCANMASTER SEE'S ECM VOLTAGE NOT BATTERY OR ALT .. 4 VOLTS OVER 12 IS WHAT MOST GOOD BATTERY'S READ OFF THE SHELF .

NO they dont they read 12.6 volts

 

[RIFF RAFF]

THE 72 MONTH INTERSTATE MY SHOPS SELL DO ..

might want to check your volt meter.even with a surface charge you wuldnt get over 13.1 each cell in a battery is 2.1 volts

What voltage do you see at the battery when it is running?

 

[RIFF RAFF]

What voltage do you see at the battery when it is running?

ANY WHERE FROM LOW 14 TO MID 15

 

[LEGACY_GN]

It's putting 15. 3 to the battery.

 

[RIFF RAFF]

It's putting 15. 3 to the battery.

AND IT SHOULD .. GOOD NUMBER .

 

[RIFF RAFF]

NO they dont they read 12.6 volts

BOBBY YOU ARE CORRECT 12.61 IS AVERAGE ON THE SHELF .. I SHOULD OF POSTED THIS WAY .. OFF THE SHELF & IN THE CAR RUNNING ..DID NOT MEAN TO CONFUSE .BUT IM STILL SAYING HE IS OK .

 

[Eticket]

sound like a bad regulator to me. that high of voltage all the time isn't necessarily a good thing. you can literally boil your battery.

 

[Ttype6]

It's putting 15. 3 to the battery.

So,you see the same voltage at the battery as you do on the Scanmaster?

 

[LEGACY_GN]

I mean it varies. It drops to 14.8 when the fan kicks on.

X2 on that.

14.8v max at the battery.

And you get the same voltage at the battery and Scanmaster?

 

[LEGACY_GN]

And you get the same voltage at the battery and Scanmaster?

No, but close. I should mention I ran a new 4 gage cable from alternator to batter for the increased power of the 200 amps.
