I know I post up a lot of issues about my truck but I'm just trying to get it right I'm having trouble with my idle.....if my idles at 750-800 my battery Brake and oil light turns on and my charging systems good I just checked it not to long ago so right now I'm running @ 1k rpm all those lights are off Has anyone has this issue? Pls lmk wat can b the problem.. Thanks
sounds like your alternator isnt putting out enough amperage... but it wouldnt explain the oil light... could also be an ignition issue... (the cylinder)
When I tested it, it was putting out the right amperage but the lights were on...so I might have to replace my ignition cylinder?
(sigh) that oil light at idle probably means you have low oil pressure. Since it goes away when the engine revs higher it means the pump is producing more pressure. Excess bearing wear, be it mains typically , but rods can wear too. Rebuild it. Or pay someone to
Sounds like a alternator and or voltage regulater failing ... The alts not putting power out do not be concerned with the lights . The brake and charge are wired together Theyll both come on together if current is failing High idle is the result of a alt not giving power or voltage reg going your light are coming on because there is a miss somwhere in the charging system ..they go away at high idle likely as a result from them receiving enough voltage for the alt .. Also check your fuse labeled engine if u have it ..make sure it's good and tight ... Inspect power supply from battery to alt and all grounds ....a alt can give a good reading and be bad diodes in the alt get hot and can act up same as bad or worn brushes in the alt Bad worn or dying batt and cables or incorrect groundings can play hell on a charging system. When idle falls to regular range 750 it's probably not producing power truck starts to freak from low voltage ... The dizzy and coil are sucking all the juice at that idle speed 750 and there's little left over for everything else voltage regulater sees this and starts the help me I'm hurtin lights ... This would be my theory
My motor has been rebuild not to long ago all was changed rod bearing And all that other ****....so oil pumps going out? Mayb ill pull off my alternator to check if its going to read it right....I checked all my grounds from the rear of the head to the alternator ground to the battery ground all the grounds I can think everything's tight no loose ends....I also did a old school test by unplugging the battery motor still runs....ill go back and check all my wires and ill just pull off my alternator to go get it re-tested THANKS GUYS....lmk on other input
Don't worry about any of your lights n your dash . It's common for tpyotas and Hondas to light u like Christmas trees when voltage is low .. The oil pressure switch is electric circuit and if you had power a lot more power accessories say like a four runner there'd be a lot more gauges to light up .. I've seen bad alts leave electronic controlled auto trans cars not shifting because of a bad voltage supply. Stick it in the oven for an hour then take it to get tested . While its hot about 120 degrees
You check your voltage regulator . Charging system relies on that to monitor and control voltage supply Still convinced there's a gremlin in there somewhere
Im determining rpm from my tach...sometimes idle drop low as low as 500rpm my average rpm is around 700 -800 900 sometimes Checked it all
Will it run without the fifteen amp engine fuse plugged in. If the charging system is good .. Then there is a possibilities of a wire either touching or grounding out possibly burnt .. 750 to 900 rpm is good. 500 is not . Alternator is not exciting the trigger wire to create voltage at that speed That could trigger some dash lights Just on a random note my oil pressure sensor hasn't been hooked up in years don't even have the sensor in the block . And the dash light doesn't come on . Shows you how crude of a alert safety system it really is
Indeed on ohms scale X psi .. The light is still grounded buy the dash harness wich would have led me to believe it would come on . If it was unplugged . But never did . Cause. I Didn't want to stare at a light .. That spot in the block would be ideal for a oil pressure gauge of a numerical readout .. Would be a great useful gauge
Correct If you have the idiot light (no gauge) It's wired so the lack of a sensor turns the light off. If you have the gauge, you don't get a warning light. it's not there. No need: you have a gauge.
