Does any one have or can tell me how the air sensor work, like how does it send signal to gauge. does it do it electrically, like Ma? and how does the gauge convert it to analog. thanks any help will be appreciated.



Rod , south bend. 01 road glide

 

It uses a varistor to modulate the current that the gauge responds to.

 

Can I buy a air pressure sensor to use that gauge ,

 

it works off the muffler bearing
