Civic 1992 LSi strange coolant gauge raise
Hello everyone,
On my Civic made some "tunings" like LED ribbon instead of bulbs behind the gadgets. After that, or by coincidence, the coolant gauge stared raise to "H" instantly after ignition key turns on contact
Checked coolant temperature sending unit by this way
The unit works normally, from 152 Ohms to 80 Ohms after few minutes of working engine. Gauge raise when Y/W wire connect to ground. After disconnect from ground or sending unit - goes to zero.
Is it possible during dismount/mount of hud to be broken somehow. I mean there is some resistor and diode like cener, did they do some voltage diver for the gauge?
Please advice folks.
Thanks to all responders in advance!
