How long to recharge
A harder question since I don't know how much the starter motor on a
50cc scooter draws: How long does it take a 1 amp charger to recharge what is removed from the battery after cranking for 1 minute? Same question but for a 2/10 amp charger when on the 2 amp setting? When on the 10 amp setting?** |

You know, I think I have one of those that I've never used. This would be the time! Clamp on meters (of the kind we can afford) If it's suitable, and even if it's not, I bought it at....wait for it..... Harbor Freight. They have them now for 12, 14, and 16 dollars. I don't remember which I bought. At that difference I should have bought the best one maybe, but it might have even been on sale to get me to buy something I don't need. I had a probably better quality attachment for a meter that clamped on, but I think I gave that away after I got this. It may have required multiplication or division, and I said when I left the sixth grade, "No more of that for me." Looking at the pictures, it may be hard to get it around the wire. I looked at the wire today.... maybe not hard. Of course, I'll have to hold the brake and the starter motor button and look at the meter at the same time but that will be easier than spraying ether, because the air input is under the rear "fender". http://www.harborfreight.com/digital...ter-96308.html 12 http://www.harborfreight.com/digital...ter-95652.html 14 http://www.harborfreight.com/digital...timeter-1.html 14 http://www.harborfreight.com/clamp-o...ultimeter.html 16 Cheapest one: 12 6-funciton Clamp-style multimeter lets you make instant tests and measurements without disconnecting wires.

Put the meter clamp around the cable, on the correct setting. Engage the ignition and read the meter under peak stress. I guess that will give the max amp draw across the cable to the starter.

There are simple DC ammeters that don't "clamp" on the wire but just pass the wire through a slot or groove, and measure the magnetic flux created by the current flow. Kinda like a compass with a light spring on one side of the needle and a marked scale on the other. |

A clamp on AC current meter can be made using
Wire coils in the sensor. A hall effect sensor is needed to make a DC Clamp on current meter. Fundamentally different technology. |

I was thinking about getting one because of the DC amps, then read the specs on it. The temperature could be way off. I could not get my head around the part where it says so many digits either. I think I may have an idea about it, but first time I have seen this. I do have good meters for other functions other than the DC amp clamp function, so no need to buy one that is totally accurate,but don't want one that is 5 to 7 deg C off. |

And if he's cranking for 1 minute, time to get the engine fixed. Starters don't take nearly as much out of a battery as some people think, assuming the engine starts normally. Even a car size starter today is on the order of 1000W and only cranks for a couple seconds. |

At one side of the break he had amps, but not on the other -- so the wire break was located. He sold the meter on his web site. Is my recollection correct? I'll look for the video later. Can't use an ammeter to check for an open, but there was a kit made to locate shorts that worked that way - it had an "interupter" that took the place of the fuse and turned the current on and off - pulsing it, due to the short (in reality, just a self resetting thermal breaker.) I still have the meter portion from mine - the breaker went up on smoke about 20 or 30 years ago. The wire would have a pulsing current on the battery side of the short - and no current beyond it. They worked reasonably well for a while - - - - This is the kit he used (inline-fuse that cooled and reset & amp meter) . The wire was shorting to ground. http://realfixesrealfast.com/short-finder.html This is the video I mentioned: (22:00) https://www.youtube.com/watch?v=TZrCrBx4uFY Here he finds an intermittent where the wire was broken: (22:00) https://www.youtube.com/watch?v=ux_9782rOsI I get all my electrical verbiage mixed up :) I didn't look at the video, but he would find an intermittent short where wire insulation was damaged. Locating an intermittent open requires more sophisticated equipment. Yes the equipment was more sophisticated (scanner / labscope). He still used the amp meter you mention to track things down. When he opened the cable bundle to inspect - the intermittent wire broke. He could reproduce the problem near the computer module. |

Same question but for a 2/10 amp charger when on the 2 amp setting? When on the 10 amp setting?** If the starter draws 20 amps for 1 minute it will take 20 minutes to replaxce the charge at 1 amp charge rate You need to know what current is being drawn and what current the charger is putting in - which has very little to do with what size the charger is. And if he's cranking for 1 minute, time to get the engine fixed. Starters don't take nearly It often doesn't engage, but it only takes me a second or 2 to notice that. I release the button and within a time or two more it engages. After that, it starts if it's going to in 5 or 10 seconds. Once almost immediately. as much out of a battery as some people think, assuming the engine starts normally. Even a car size starter today is on the order of 1000W and only cranks for a couple seconds. |

I don't know how well it works and I don't have much need to measure such things, and somewhere I have a meat or candy thermometer anyhow. I have a few digital thermometers that connect to thermocouples and I've used one of them in the kitchen to check the oven temperature in real time. I was able to see how much the temperature would go up and down as the gas burner cut on and off. I also used it to check the refrigerator to watch the temperature recover and see how much time it took. You can also stick the end of the thermocouple in some plastic wrap, put the end in your mouth and check your temperature. You can also observe your temperature change as you watch a speech by a politician on TV. (€¢€¿€¢) [8~{} Uncle Hot Monster |

You can also stick the end of the thermocouple in some plastic wrap, put the end in your rectum and check your temperature I changed your text to bring out your true thoughts Unc. Actually the plastic wrap is optional. I have a question when young and playing Doctor did one consider sterility? -- Tekkie |

You can make everyone think you're Burka Boy using a sock. You don't have to use the plastic wrap if you stick the thermocouple under your arm. When I played doctor as a kid, I got in serious trouble for using a real scalpel. When I last played doctor I made believe I was a gynecologist. It's always best to have a willing make believe patient. ヽ(€¢€¿€¢)ノ [8~{} Uncle Scandalous Monster |
