No, but if that accessory you are checking only has power when the key is on, then you need to check with the key on. Does that make sense? It really depends on how they are wired. Some things are fused after the ignition "ON". For those things the key would need to be on to check power to the fuse. If you're not sure you can just leave the key ON while probing the fuses.
Hi friend!! Recently I buy the same test light. Wich specific test can be done with this test light and wich not? The manual give poor info about it!
thanks so much. very well explained!
Ha. I've used it to test cam/crank signals but not injector pulse. Thanks.
3410 innova test light good enough to test voltage and ground.
Thanks for the video brother
Good tutorial, thanks.....
thanks
Can I ask you one question, when checking a fuse do you need for the car to be on? Thanks...
