Yes and no. These videos were omix or crown. I believe they were crown. Both take 12v and step down to 5V via a current regulator in the fuel gauge. I recently tried to order these and they’ve changed the design. Now both gauges need 12v. I’m working on videos for those as well and a product to help troubleshooting and calibration.

@@engindude25 Ok. That's what I thought too. Tested this morning and output of fuel gauge on A post is 12V. Not an electrical engineer but trying to put together a test rig like your video. Any links to that rheostat/potentiometer? Thanks.

Michael Taylor the rheostat/potentiometer will work the same regardless of whether the gauges are 5v or 12v. I’m no electrical engineer, so you’re in good company.

@@engindude25 That makes sense, but when looking for one I assume it has to be good to 100 ohms or so for the bench test and works on 12volts? That way it will substitute for the sending unit going to 73 ohms or so? Also, are the ohm reading for testing the gauge itself to be used on the bench unpowered or with 12v and a ground attached? Thanks.

My gauges are doing well and I did my dads Jeep shortly after. I do recommend using the converter still. If I recall it’s limit is 5A. It does put out amps, the device draws it. If the gauge were to loose ground it could try to draw as much as possible, but the internal limit will trip at 5A. You gauge doesn’t have a limit. It just burnt up previously. If I were to recommend any addition safety limit I’d say adding a fuse before the converter would be an increased means of preventing the huge from drawing too many amps. I’m not familiar with the tobsun device mentioned. I don’t see the 5A limit being an issue.

@@engindude25 Same question here, you mentioned the 5amp may burn up the gauges and if you had thought about it you may have gone with someone smaller. I found the Tobsun 5V 3A 15W which pushes a little less than the 5V 5A 25W stepdown used in the video. Did you mean to say a ".3 milliamp" inline fuse before the gauge? I don't know anything but isn't a milliamp super small amount compared to 5amps?

Blake C i may have misspoken or it was misunderstood. These devices don’t “put out” amps. The gauge will draw amps and these regulators would trip at 5A. They do reset tho. Would it be wise to use a lower Amp voltage regulator in the even the gauges would burn up at say 3A, sure but what size? At the time I didn’t have a means to understand the typical amp draw. If I was going to increase protection I would put a fuse holder upstream of the regulator and put a 1A fuse in, unless that’s too low for normal operation. Then possible bump up a bit. Make sense?

corvettedan22 just the particular gauges.

corvettedan22 yes

MrElPoderozo1 you don’t have to. The voltage converter/regulator used in the video just can convert unstable 8-40 vdc to 5 vdc. If you don’t want to use the converter used in the video, you have to supply roughly 12v to the gauges per the factory wiring diagram OR just supply 5V to the gauges. As long as your source is DC and depending on the method you used as described here, the source really doesn’t matter. Does that help?

@@engindude25 Yeah I want to make the same set up but I didn't see your power source. So I assumed that you went all the way to the jeep bsttery from the bench. Is that what you did,?

MrElPoderozo1 yep!

@@engindude25 thank you😊

@@engindude25 I was wondering if you can help out by providing a part number for the potentiameter or recommend one from Ebay. I was looking in Ebay and they are like in thousands 5K etc... all that language is jeberich to me, lol. So if you can provide me with some part numbers or recommend me one It will be appreciated. Thank you.
