How many watts is the ADM? Looking to purchase the 15 ohm resistor that is next to the thermal fuse. The number on the resistor is 85463 however the electronics vendor states that is a proprietary number with no other information available about it.

 

A resistor's physical size indicates its Watt capacity. But you can always replace it with a resistor of the same Ohm rating and higher Watt capacity.

But resistors don't usually have numbers - they usually have colored stripes, or the Ohm rating printed in plain text.

Steve,
Thank you for the reply and information. The resistor that accompanies the thermal fuse is not marked except with a number (85463) which is a proprietary number/resistor (according to a couple of electronic component companies). The body of the resistor is only about a 1/4" in length. I am experimenting with the resistor wattage (since that is the only part I could not find out) and I will move up in wattage until the thermal fuse does not blow. I am starting with 1W and once I have it dialed in I will post my results, components used, part numbers, and business where I got the parts.

 

That's not the right way to ID the resistor, and that's not how the module's internal fuse works.

 

I know you are knowledgeable about the OBS vehicles but you are NOT the definitive authority on everything. Instead of making condescending comments on everyone's posts (because they say name something wrong) provide helpful feedback or say nothing. While capacitors generally have markings on them to identify them (and not numbers) this is not always the case. I know you have looked inside the ADM from your posts and if you recall the capacitor associated with the thermal fuse only has a number (85463). The capacitor is considered a thermal capacitor due to how it is used in conjunction with the thermal fuse (connected with the thin copper heat clip). Electronics are air cooled in most cases (and this one) which is why this capacitor is in such close proximity to the thermal fuse AND connected to it with the copper to enable the capacitor to dissipate its heat thru the copper to the thermal fuse so the fuse can blow (thus saving the capacitor and the rest of the circuit.
Again, I appreciate your knowledge because you do have a lot just don't like your mightier than thou attituded towards me and others.

 

I searched the part number and ended on a Honda Forum. From what I read it "MIGHT" be a 1 watt resistor. I might be wrong

 

Thank you for the response and looking into it. I also found information about it on a Miata site but nothing about wattage. However, talking with a couple of electronic tech support people, they both said most likely 1/2 - 1 watt. I figured I would try out the one watt with new thermal fuse and see if it works. The tech fellas also said proprietary items are also used by others but with just a different number applied to that particular user. Once everything gets here I will put it all together and post the results.

 

Nothing I've posted was condescending. Everything I post is my opinion. You've been saying resistor - now you're saying capacitor. Those are totally different components, like an engine vs. a transmission. No, neither a capacitor nor a resistor is considered "thermal" whether or not it's associated with a thermal fuse. So this thread is degrading into nonsense. Good luck.

 

while wattage can be determined by size in many cases. the "resistance" (ie ohms) are critical values as regards the circuit THIS applies to resistors. and as the name suggests they resist the passage of electrons.

capacitors on the other hand, store voltage for a period of time and then do that over and over. It's value is also important as regards the circuit is in, and it is measured in farads, from "micro" on up. Identified by numbers or color bands or size or....there are specific types of capacitors and many types are not interchangeable.

blindly changing components with out regard to values and power handling will render your unit, broken or worse, you may let the smoke out.
