Hi All, Just want to throw this up for comment. Have a new Honda GX200 powering a splitter. Would like to add an hour meter to track usage for services. There's tons of self contained ones on eBay with the battery built in, & the wire that wraps around the plug lead..... Catch is the battery's internal and has a life of 20,000 hours, OR 833 days. There's also these, 12-24V 10 to 80V??? Wondering if the above one could some how be powered by pulling a small current from the kill switch circuit? Cheers. |

Hi Phil23, Normally for older engines, the kill switch just shorts the ignition (points or Hall Effect circuit) from the magneto circuit to earth. No DC as such involved. Not sure with modern ones, but looking at photos of the ignition system for the GX200, I would say that there would not be any 12V or above DC present to run the meter. I think the self powered one would be the way to go. There may be a way of attaching a larger capacity battery to it. The trouble with these type of meters is they don't often tell you how hard the engine has been running. Sorry I can't be more helpful Brian ChopperP |

Trouble with the self contained ones is they are completely potted, the battery included. Went to great lengths to neatly fit one in the side cover of my EU10i, only to have it quit after about 2 years. Looking on RS, there is a huge variety, including mechanical that work on different input ranges, some AC some DC. Guess I should put the multi-meter across the kill switch & get a rough idea of what's there. |

An oscilloscope if possible would be better. Probably find a nice spikey waveform there. ChopperP |
