BakoBanshee Posted March 8, 2004 Report Share Posted March 8, 2004 Heys guys I went out and bought a digital multimeter to test my stator at the four-wire connector. I have a printout from BenBB about what the readouts should be for each coil( colored wires). My question is at what OHM setting should the meter be set on to test them? For the OHMS settings there are 7 different settings that I could switch it to. They are as follows... 1.) 20M 2.) 2000K 3.) 200K 4.) 20K 5.) 2000 6.) 200 7.) This last setting is indicated by a black mark( the others are green) as well as by a line with different right angles. Last, this might sound like a stupid question but do I simply touch the coils with my meter, or do I have to be kicking the engine over while I touch the coils? Thanks for any help.

nater006 Posted March 8, 2004 Report Share Posted March 8, 2004 I can help you with the first half... You want the setting that's close to the Ohms you're expecting to get. The K is just a fancy way of saying "put 3 zeroes here" and the M is just a way of saying "put 3 zeroes in front of the value (and a decimal point..)". If you have 3K ohms, it is 3000. If you have 3M ohms, it is .0003 ohms. If you're expecting to get a value between say 3 and 20 ohms, set it to the 200 setting. If you're expecting to get a value between 0 and 1 (e.g., .000x) set it to the 20M setting. It'll measure the same at any setting -- however, the accuracy returned may be severly rounded off if you're using the wrong setting. If you're measuring something thats .032 Ohms, having it set to check in the 200K section will just round it to "0" on your readout probably. Sure thats rounded off relatively accuratly but if the allowable range is like +/- .002, well... just seeing a 0 kinda sucks! you get the idea... Good luck!

BakoBanshee Posted March 8, 2004 Author Report Share Posted March 8, 2004 so let me see if i get this. BenBB's post gave the following numbers. Do I have the right settings figured out? Charging coil 13.7 - 20.5 Ohms. Setting at 200 Pick up coil 94 - 140 Ohms. Setting at 200 Lighting coil .26 - .38 Ohms. Setting at 20M Thanks for the help Nater006. Does anyone know the answer about whether to kick the engine over while testing? Quote Link to comment Share on other sites More sharing options...
dnhyoung Posted March 9, 2004 Report Share Posted March 9, 2004 to test for the last set of resistances, you would want to be set a 200 ohms. You don't need to be kicking over the bike. Ohms is just a measure of the amount of resistance in the line between point a and b. if you were looking for voltage/amperage, then you would have to have the bike running.

nater006 Posted March 9, 2004 Report Share Posted March 9, 2004 Play around with the different settings on that multimeter. The 20M setting will probably work fine for that last one -- it just depends on how many decimal places it shows. The 200 setting might work just as well if it goes out to 2 decimal points (i.e., 182.88) since that's all you need. The multimeter will read the same amount either way -- most of 'em just use the different ranges as a way of placing the decimal point in a different location and giving you more accuracy where you need it -- either in really large numbers or really small numbers Quote Link to comment Share on other sites More sharing options...
svtkid78 Posted March 9, 2004 Report Share Posted March 9, 2004 the ohms like he said is only checking the resistance. if you need to check the output you need to be in volts ac Quote Link to comment Share on other sites More sharing options...
