I have read many postings on this issue.

My Viper has been harder on fuel and slower since the begining of the season.
It's a 2003 Viper ER. My battery went dead the other day. I unpluged the battery started te machine and put the tester to it. All I was getting was 8 to 9 volts. I even noticed the RPM gauge keeps resetting itself since there isn't enough power being supplied.

I changed many parts
- Stater plate
- Voltage regulator (on the right side behind battery)
- CDI unit

Still pushing same voltage 8 to 9 only.
Do you think a wire is causing this?

My next step is to change the wiring harness, I don see what else?

Any help would be appreciated

Thanks in advance
 

ok, first off you need a good battery in a viper ER to run the guage unit, its the way the er is wired versus the std vipers. before we go any further with this, install a new battery in the sled and restart and check running condition.
 
I will be picking up a new battery tonight. I recharged the old one but I will toss it.

When the battery is unpluged should the voltage be higher or it needs to be hooked up in order for everything to work properly.

Thanks
 
the battery needs to be charged and hooked up in order for everything to work right. (just found that out on my 2002 viper er) also if you end up needing a wiring harness pm me
