Fixed - 97 1Z buzzing 109 relay
Hey guys,
***FIXED*** - Ended up being the nut on the mounting plate for the ECU which was lose. For those that don't know (like I didn't) that's also where your ECU goes to ground
Summary:
Friday night - wife goes to start car after 6hr work shift, glow plug light doesn't come on and buzzing from dash. Car cranks but no fire. Starts immediately when jumped. Drives car home and same thing
I come home and isolate sound to said relay. Pulled off housing and basically changed the shape of a braided wire to push onto gate and keep it from opening as the buzzing sounds was a result.of gate trying to close but failing. Leave overnight.
Car works for drive to work, drive after work, drive to and from Edmonton (to Pick N Pull for new relays) on Sunday, about 120kms on Monday, sits all day Tuesday
Car is completely and utterly dead Tues morning. No lights left on only possibly the rear defrost but that has never previously caused issues (seems to shut off fine when car is turned off)
Tried swapping power relays as I figured the closed gate is causing constant draw.
New relay now buzzes and original problem is back
Alt is putting out 13.8V, batt at rest is 12.4, I'm getting 12V to 30 on the relay and with the buzzing one in I get 3V to 87 (slot 6) and 10.5V to 85 (slot 5)
With modded relay, I get 3V to 85 (slot 5), 13V to 87 bottom (Slot 6) and no V on 87 top (Slot 1) but car runs and provides 13V to 30
If I turn the fan and defrost on then 87 top (Slot 1) goes to -1.5V and the 87 bottom (Slot 6) and 30 drop to 11.3V
Possibly unrelated but with rear defrost on there is a noticeable loss of power
