Fuelk injector tester, anyone built one? Options

[scotty b]

I'm guessing someone has built a fuel injector tester by now. I have an old Bosch mechanical injector tester and was thingking today about making work on electrical ones, problem is I don't know how much voltage/amperage they get. (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) I doubt they get a full 12v, and I really don't want to ruin any trying to find out (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) .HELP?

yes i built one, not very hard. one way is two build a 5 volt regulator on a switch, the hook it up to the injector, push the button to open the injector. if you are not sure how to build a 5 volt reg search on subtech on the internet they are a rc model sub ( as well as other remote stuff ) place that sells all sorts of electronics, they are currently being disturbuted by mikes sub works, look for the bec or some thing like that. it will supply one amp at five volts with a supply of 8 to 24 volts.

i built one and used it to open my injectors to pump cleaner through em, had the reg very hot to the touch by being open and drawing i think two amps for like 5 mins at a time. never even warmed the injector, but i think they run off of 3 to 4 volts in our cars
