using diodes to step up voltage


Recommended Posts

I'm at work right now and we are slow so I decided to make my own voltage booster. I know a local company makes a plug and play harness using a diode on one of the wires on the alternator harness, so after I did some bench tests I installed it. I have a 2001 Impala 3.8L and it works great. I am using 2 6amp diode in series which takes me to 15.2 volts warmed up. I had a XS Vcm in my 97 blazer with no issues @ 15.3. I'm looking for opinions of this mod before I leave it in long term. I'm still waiting for my H/O alt.

lower tuning is just hard. I was surprised how loud 145 sounds at 35hz, and how quiet 145 sounds at 50hz.

proof please...typically a voltage booster needs a MOSFET or other transistor in addition to the diode. and usually a cap to reduce ripple.

Im not the first to do this. It tricks the regulator in to producing more voltage. Check out the ZZP VOLTAGE BOOSTER....

I've had this done on my 01 Impala LS for the last 2 and a half years. My driving voltage is 15.2, and when cold it's as high as 15.6 sometimes, haven't had an issue with it. I notice my heated seats along with the rear defroster work a lot better.

Yea it took some tinkering to get exactly what I wanted. My XS VCM had 15.3 as a threshold so this is what I wanted. so far the highest its went up to is 15.5. My alt ships in the morning so soon my charging should be legit ;)

Its orange, at 15.6 its red. RF amps shut off at 16.0 :( I had one the was 15.6 volts warm but cold was ~16 volts and my amps wont even turn on lol.
