[The Seldom One]

Got my bike back together after waiting on some parts and being a little too busy. After starting it up, the bikes Oil and Temp light didn't turn off. Checked the oil level and coolant level again just to be sure, both were fine.

I had just adjusted the valves and tore up the carbs. Oil and coolant were changed, new filter, etc. I double checked all my wires and hoses before starting up and there were no leaks before and after starting it up. For the few moments I let it run (10 seconds or so) the engine sounded fine, no knocking, slapping, etc. The high beam, turn lights, fuel gauge, tach, etc all functioned properly.

I had read that the oil and heat light form some kind of circuit and both lights being on could be due to a bad ground along that circuit.

Does anyone have some suggestions for trouble shooting?


TLDR: Started up, oil and temp light stays on.

-oil + filter and coolant were changed
-valves adjusted, had to remove rad. hoses, mounts, etc. on right side.
-replaced cylinder head cover gasket
-replaced spark plug gaskets
-replaced water pipe o-ring that going into cylinder head
-carb cleaned
-the rest of the gauge cluster works fine.
-no terrible noises while it ran.


I thought I would post this up right now and maybe get some input while I continue doing some searching.

Thanks




Edit:
In the service manual under water temp warning system

"The water temperature warning light goes on when the ignition switch is turned on and goes off soon after the en- gine starts running (oil pressure switch off) to ensure that its circuit functions properly. The warning light also goes on whenever the coolant temperature rises to 110 ∼ 120°C (230 ∼ 248°F) when the motorcycles is in operation. If it stays on, stop the engine and check the coolant level in the reserve tank after the engine cools down."

I may be reading this wrong, but It seems to say that if the oil pressure switch is off, then the water temp light will go off. So if my oil pressure switch isn't turning off then both lights will stay on.
IF this is true, then for this to be the cause there would need to be a wire from the switch grounding out somewhere?
Somebody correct me if I am wrong.

-In the mean time I am going to check the local auto parts store for a cheap oil pressure gauge and plug that in, see what I get.

Edit: Should have brought the Switch with me, none of the fittings are the correct thread size. Looks like I'll pick this back up tomorrow.
