I used to grease spark plug boots so they wouldn't stick. Another benefit was to keep dampness out. Silicone grease is hydrophobic, so condensing moisture wouldn't creep under the boot. Other kinds of grease could have lubed and kept moisture out, but voltage from the wire might have followed...

Mechanical TV tuners had to handle VHF/UHF signals of very low voltage and current. The contacts would perform fine immediately after assembly, but although they were kept dry, oxidation could cause trouble down the road. RCA electrical engineers found that silicone grease kept them working down...

They used to say don't grease the posts or cable terminals of a car battery. There's a hairline crack where the rubber case meets the battery post. I'd prevent corrosion by using a q-tip to cover that crack with silicone grease. I was careful not to get any one the post until I read an article...

In 1968 I participated in an international tour with a gentleman named Davy Crockett. One morning we were sitting on the ground conversing with a 4-year-old villager. Crockett got up to speak with other tourists. A second later there was an explosion, and everybody knew he'd wasted a perfectly...

Yea, Julet connectors! When I removed the cadence sensor, I remembered my automotive hose removal pliers. https://www.amazon.com/dp/B07G5QSQFQ If they would work on Julet connectors, it would have been a breakthrough. They wouldn't work.

Cycle Analyst wants to know how many poles you have so it can display your cadence. I don't need that because I have no gearshift. It's always 21.25 feet per crank revolution. If the speedometer says 9 mph, that's 47,520 feet per hour, or 792 feet per minute. Dividing by 21.25, it's a cadence...

The original controller missed shifts. I put on a KT. The manual said nothing about the number of magnets in the cadence sensor. These 12-magnet sensors are supposed to be nearly universal. The 12 magnets are supposed to provide a quicker response.This new type also has "double Halls."

More than 3 years ago, I got an aftermarket controller for my Radmission. One advantage was that I could have the throttle available while pedaling without PAS. Today I tried PAS on a hill. It cut out for about a third of each cycle. I pulled the left crank arm and removed the sensor. It's...

After I filed the depth gauges and it made little difference on stumps, I ordered a chrome-plated chain. I haven't used it. Before it arrived, I discovered that I hadn't gotten the old chain properly sharp. Near ground level, stump wood can be like steel. A wafer 1/8" thick can be incredibly...

The Hall sensors in the motor? Would they cause the tail light to fail? On times when I got a bumpy start, I was unable to repeat it. I suspected a bad connection. I recall that the controller has a fat cable to the motor, a 5-conductor cable to the tail light, a 2-conductor cable to the...

Oiling with a squeeze bottle was messy until I stuck a 16-gauge needle on top. I can stick it into the groove in the bar and squeeze until the oil rises to the top of the groove. I repeat it in a couple of other spots.

Customer support asked the same thing. When I pulled a brake lever the brake light lit. When it went out, I figured that showed that no brake switch was closed. Nevertheless, I popped the connectors and the motor still wouldn't run. There ought to be a tool for opening e-bike connectors! This...

Aventon replaced the controller and taillight last August, 9 months ago, under their warranty. On the invoice, I noted the list price, something like $65. That's not too bad, if they can still supply it. The OEM controller on my Radmission was flaky. An aftermarket replacement has been very...

This house was built with 4 coal-burning fireplaces. My grandfather went to a central oil stove, then dug a cellar for a gas furnace about 80 years ago. Since then, I'm aware of only one time when power was out long enough for homes to get dangerously cold. If it happened again, it seems a...

I cleaned the contacts. Now the brake and tail lights don't work. I hadn't disconnected that cable. I took the controller out again. The taillight connector was tight. Everything was clean with no sign of cable damage. The display, speedometer, and headlight still work. It seems like the...

My Abound worked fine when I shut it down at 8:30 last night. At 8:30 this morning, the motor wouldn't run. The display had no troubleshooting help except to say the battery is at 92%. The speedometer works. The brake light is off unless I pull a lever. There was no response when I substituted...

The energy difference per cup would be a fraction of a penny on a power bill, but it would make a difference on emergency power. Ice storms can cause power failures. At those temperatures, my gas furnace would need to provide 12,000 btu per hour, on a 15% duty cycle. With space heaters, that...

Can yours stop at 60C? Heating only as much as I need saves nearly 2/3. That's what I was after, in the event of a power failure. https://www.amazon.com/dp/B0B4JRCLW4 This is what I've been using for 3 years. Heat distribution is so slow that if I want approximately 150 F, I watch intently and...

1965: God said to Abraham, "Kill me a son." Remember the siren? I just bought two! They're marketed as freezer alarms. If an electrical receptacle goes dead, a 9V battery sounds the siren. Brewing coffee one cup at a time was a dead giveaway that I'm a snob, so I switched to instant years ago...

My father used one until 1956. In 1968, the state employment agent told me there were lots of jobs, but none for veterans. I answered a want ad from the country club and got hired because they didn't ask questions. I found quick affinity with the greenskeeper because he'd been a Marine in WWII...
