![]() Hello TBers,
Planning to adjust mixture or see if it's set right. There is a thing called "Volvo special tool part #9995280" As I can tell it's hard to come by this one, so would something like circuit tester with led would work? Ex: https://www.amazon.com/OEMTOOLS-2588...3523007&sr=8-9 If not, any suggestions?

![]() ![]() Here's mine. It is quite literally just an LED soldered to two wires. One goes to the pink wire in that 2 wire connector I was telling you about, and the other goes to the positive terminal on the battery. As you turn the adjustment pot on the AMM it will blink on and off. You adjust it until it is staying on about the same amount of time as off... a constant steadyish blink... I would think any LED light would work...so your link would probably work although it may be overkill. You want the car to be thoroughly warmed up when you do this.

![]() One side goes to the test connector (red or pink wire) and the other side goes to 12v... Basically the ecu grounds the test connection when it senses a rich condition, which lights up the light, then un-grounds it when its lean. It should cycle rich for a sec, then lean, back and forth.

![]() The resistor is just to protect the LED in case you accidentally just short it to ground too long. It is not needed.
