tach-o gone wacko!
my tach just started jumpin up and down today out of nowhere.... then came to rest at 0... and eventually started working again but displaying the wrong RPM. i suspect that its NOT a fault in the actual tach but a fault in the sender unit or connection between the two. can anyone tell me what feeds the tach its output? (is it off of one of the coil triggers or am i remembering that incorrectly.... and does it pass to the ECU before going to the gauge cluster?) ive been having problems with bad connections at the sender units for various unrelated things recently... i guess i need to just unplug the entire harness and clean all the connectors one of these days cause things are going bezerk. thanks for the help as always . -heath
