Hi all,
I'm new to this forum and would like some help related to a new computer i just installed in my car. The tachometer doesnt work because it requires a 30 volt square wave signal but the tacho signal from the computer only provides a 5 volt square wave signal. Apparently i can use a 2n2222a for this, I have tried these circuits but with no success:
Any help would be greatly appreciated!
Thanks
