Laptop isolation

[dee004]

Heres one for the electronics guy's. I was reading through the information with the AutoEnginuity laptop software and it mentions that if using the laptops power cord to be sure it has an isolated cicuit to prevent a ground loop which could damage the ECM or laptop electronics. Would using an inverter to plug the laptop into be considered an isolation transformer or would an isolation transformer in conjuction with the inverter be required?

I'm with you on that one. I always run it off battery but on long trips if I want to do some monitorring it may be an issue. I think I will send them an e-mail and see what they say.

Just went to the AE site and drilled down through the FAQ's to some rather disturbing photo's they have posted showing the damage which can occur without an isolated ground. Think if I need power while it's connected to the OBDll it'll be my jump booster powerring the computer so there is absolutely no chance of a ground loop.

have you tried the Laptop charger bypass kit from Walmart? GE Indoor Outdoor Extension Cord 50' Extension Cord, General Purpose Extension Cord, Grounded Extension Cord

worked great when i reflashed my NAvi and was too lazy to get into and out of the truck a dozen times
