Proper Volts at battery 99 GSX?

[burtshaver2021]

Hi, I have a 99 GSX RFI, not sure what the volts should be reading at the battery at idle? I tested and it was 13.2 to 13.3. The reason I tested was last time we were out we had to restart the machine 3 or 4 times due to boats coming in while we were leaving the no wake zone and battery got low and would not start

Tested my 95 xp at idle 13.7 volts

97 GSX was at 13.2 at idle. Maybe the 13.2 or 13.3 is ok for the 99GSX RFI?

Battery should be above 12V at rest at all times. 13.5 at idle is perfect and at about 4,500 rpm should be around 14V.

I will try reving it to 4500 rpm’s and see what I get. You mentioned 13.5 volts at idle was perfect, am I ok to say the 99 GSX RFI is fine at the 13.2 to 13.3 I’m getting at idle? And ok for the other 2 97 GSX 13.2 volts at idle and the 95 XP 13.7 volts at idle but I believe my rpm’s were a bit higher than the recommended 3000 on it. Thank you

That should still be fine at idle.

Just posting here some information for myself so I have it handy if needed. Battery Volts should not fall below 12 volts while cranking
