blackhat250 Posted November 13, 2016 Share Posted November 13, 2016 Tell them there is a difference,, logged , so if bother a replacement will be due, I bought some parts of Yambits, the pictures showed shiney replica parts [ bolts etc, ] an received black bolts, other parts looked cheap too, .

neversaydie Posted November 13, 2016 Share Posted November 13, 2016 Dont compare the readings between the new and the old. Resistances for the new should be: Primary: 3.8 to 4.6 ohms @20 degrees C Secondary: 12,000 to 14,500 ohms @ 20 degrees C Take the plug cap off for checking the secondary Link to comment Share on other sites More sharing options...
fishermanferg Posted November 14, 2016 Author Share Posted November 14, 2016 thanks neversay I'm not to adept at using a multimeter but the old coils that's if I done it right showed a reading of 4.1 ohms whereas the new ones were 2.1ohms what do I set the multimeter at for secondary Link to comment Share on other sites More sharing options...
neversaydie Posted November 15, 2016 Share Posted November 15, 2016 Secondary readings are in the thousands, so youll have to switch your meter to read in that range. Normally, the ohms (resistnace) range scales up in factors of ten, so hopefully your meter will have a dial that looks like this resistance range is the one with the horsehoe. Primary is measured with the dial set at 200. Secondary (12k to 14.5k), move your setting to 20k (k = 1,000) Your meter may differ and may read 100/1k/10k/100k etc. In that case, you would set at 100k as 10k would be too low. Unless youve got a really good meter with just one range Always zero your meter first, or check by holding the probes together and ensure it reads zero By the way, id be concerned that the new ones only read 2.1 Hope this helps Link to comment Share on other sites More sharing options...
