no, the current demand is too high.

... and that's why they are not getting enough voltage.
They are drawing more current than the system can supply. As a result, the voltage goes down.

If that was the case, they why wouldn't the light bulbs blow when I hit like 4,000 rpm

Because the voltage is regulated.

carshateme · 30th October 2011, 06:28 PM

Ah I see. That's the regulator, isn't it?

Thank you. Was too lazy to research it on google =D

The only reason I bought this up was because my wiring goes from battery>starter>alternator and not battery>alternator...so I just wanted to make sure I wasn't having a problem with the wiring. Although if that was the case.. I'm screwed because there is no way to bypass it.

Well I just looked at my volt meter again..it's now sitting at 15 volts now...That's bad, isn't it?

Perry Babin · 30th October 2011, 06:59 PM

15v is a bit too high. Are you sure that the meter is accurate?

Put a digital multimeter across the battery terminals to see the true voltage.
