What a surprise! Connect the two together properly, secure them properly and shocking! It works as designed! In the automotive world, we come across too many electrical terminals that have poor fit due to unscrupulous people using all kinds of makeshift probes or tools, needles, nails, whatever is handy. And then the intermittent problems start. Where connections have a decent fit but still have erratic performance, we use Stabilant 22, a terminal contact enhancer that literally fills the microscopic deviations in the surface of the terminals. Airbag deployment and sensing systems are super critical of any slight changes in resistance and will trigger a warning light and associated codes. Sometimes a drop of this chemical is all the terminals require to return it to service.
What does that electrical connector use as a means of locking? And I was surprised to see that cording was still used as a harness tie! I think when I went to A&P school, nylon tie wraps weren't invented yet!
Astonishing to think how many of those birds will never take to the sky again which directly affects how many peoples jobs will be lost due to downsizing, starting with the airlines themselves, and all the hundreds of support industries.
Yes! That's why I was surprised to see it had multiple "characterizations"...I thought it was self compensating of different attitudes and bank angles due to the capacitor sensing. Do the A300s utilize a similar system for "tweaking" the quantity?And, I just reread your post, I missed that there were 4 ground characterizations...what is it adjusting for on the ground?
Talking about fuel, it brings back memories of planes that were taxied from the hangar to the terminal with very light fuel loads, and with just a little too much speed making the 90 degree turns to the gate, how the nose wheels would skid , horribly so with a damp ramp!
It stinks when you don't have enough information to do proper troubleshooting! A few questions came to mind as I was reading this...the sensors use 10VDC, but only output a max of 30mv? Seems like that leaves lots of room for errors with such a small reference range between pressure and no pressure. And, in the picture where you are taking the current reading, I'm gathering you unpinned the original circuit, and used a jumper into the cavity so your meter was placed inline? And then no reading at all with presence of fuel pressure? This makes me think that either the fuse in the meter was open, or there is more than 1 problem with this unit! At what percentage of RPM is the fuel introduced?
They are the most reliable! We use the crimp solder and seal splices exclusively at the shop I work at. I was considering buying a DeWalt 20V cordless heat gun , instead of always dealing with a cord, especially if its a repair out in the lot. Like you said in one of your other posts...its easy to burn thru the shrink tubing with a flame.
