cleaning the fuses- a rainy day project
Took the time to pull the cover off the fuseblock and poke around- get familiar with the layout and latching in case I am ever roadside in the rain with a problem and a flashlight. The chassis is n...

My 89 Van uses the glass tube fuses.
A year or so ago, no brake lights. I look at fuse, Appears fine, put DMM on fuse, tests fine, remove fuse and it feels like 220 grit sandpaper, as well as the fuse end 'claspers' in the fuse panel. I give it a quick abrasion and then had brake lights.
Later, Out comes the Caig Deoxit d5, and all the fuses. Usually this stuff is golden, but I had to fold thin strips of 320 grit sandpaper over q tips and soak it in Deoxit D5 before the clampers obvious oxidation was able to be removed.
The 20 amp fuses were the worst. I wonder just how hot they were getting due to this oxidation and increased resistance.
The Caig Deoxit is magic electrical juice. No other electrical contact cleaner can compare. I used it on my engine sensor connectors, and some MPGs I thought I lost due to taller heavier tires, instantly returned, and my most recent smog test came back with better numbers than ever, and the only difference between this test and the last one, is cleaning the sensor connectors with Caig D5 spray and precision Tamiya swabs, and protecting them with Deoxit shield or Gold, then dielectric grease pushed into, after connector was reseated.
The Map, TPS and o2 sensor connectors blackened and shredded many a precision swab before gleaming like oiled chrome, and yes there were previously slathered with Dielectric grease. They oxidized horribly despite its slathering inside the connectors pins and sockets.
These sensors MAp and TPS only get 5 volts from the ECM, so any excessive voltage drop, and the engine computer is not able to properly decide AF ratio or spark timing.
That's my theory and I'm Sticking to it.
The Caig Deoxit products are magical electrical juice. That's my opinion but it should be fact.
