air pressure Dummy light on tac

Post by jlaw1017 » Fri Jul 22, 2016 10:54 am

where does this dang light get it's info from?

I have moved an rewired the pump from under the false tank. Moved it to under the front fearing. doing so required all new hoses an I ran new electrical (from Batt, to fuse, to switch, to pump) Somewhere I missed this light. It now turns on all the time. I have installed the pressure gauge in to the "Dashbord". I can see proper Air pressure. But something has to tell this light to come on an go off. WHERE? lol Thanks for any input. Until then electrical tape to cover it........

If it has compression, It will run.

Blue/white wire runs to the ECU - you can cut it if you want, which will kill the light.

For better details on fixing it - have a look here: viewtopic.php?f=4&t=33935

OK............... I am assuming that you have an 82 Aspencade. Please see chapter 12 pages 31 and 40 in the factory manual that is down loadable from this site. you will find the air pressure switch that controls the low air pressure warning light on the tach is located in the manual air fill manifold block behind the right side cover. The reason for the light is the 80, 81 and 82 1100's do not have springs in the shocks (they are air only). there for there must be a minimum pressure of 28 psi (page 12-33). in 83 springs were added to the shocks and the light lens in the tach was changed from red to purple and was re-labled as an OD indicator light (5th gear).
