Wasn't trying to flame you, that crimp is fine. Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside. My super random youtube channel and terrible camera work.

Skullz Posted November 21, 2013 Report Share Posted November 21, 2013 The answer can be both yes and no depending on how much wire and the size of the wire, and as long as you properly terminate the wire with a crimper you shouldn't have any problems. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
Wicks Posted November 21, 2013 Report Share Posted November 21, 2013 Combining different metals will cause a voltage drop, small, but a voltage drop. This is normal and is how thermocouples function as an example. Fuses are thermal devices and will also cause a voltage drop, again small, but there nonetheless. When done properly there will be inherent voltage drops, but they should not affect a properly designed system. Those drawbacks are worth the safety and convenience factors. As stated above, bad connections can cause massive voltage drops and resistance/heat issues which can even cause fires. Those instances though should not be blamed on the crimps and fuses themselves but user error.

snafu Posted November 22, 2013 Report Share Posted November 22, 2013 Voltage drop occurs across any connection or termination, no matter how well it is done. If terminations and connections are done properly, the voltage drop is negligible. Same thing goes for fuses - the quality ones have negligible voltage drop across them. Using a bunch of cheap lugs, fuse holders, and fuses is an excellent way to handicap the performance of your system. A quality DMM is a car audio enthusiast's BEST friend. Why is it that so few use them (correctly that is . . . )? You can quickly and easily measure voltage drop at any point in your electrical system. At the very least, put the red probe on the output stud of the alternator and the black probe on the power wire directly into your sub amp (yes, you need to use an extension). Crank the system. The reading on the meter shows the difference between the two. Factor that as a percentage. If it's greater than 3%, you've got work to do. Same exact thing can be done between the case of the alternator and the ground wire of the amp. A MIN/MAX scale is very useful here as the meter can record this data according to dynamics in the music, which sometimes isn't possible to see with the naked eye.

nCOMP1337 Posted November 23, 2013 Report Share Posted November 23, 2013 got the electrical guru himself to chime in, thats some nice info. i didnt even know you could get extensions for dmms, though thinking back i suppose my friends o scope does have like 10ft long harness on it, where as my dmm's is like 2ft, lol Link to comment Share on other sites More sharing options...
snafu Posted November 23, 2013 Report Share Posted November 23, 2013 Just so that you guys know, I fully illustrate how to properly use a DMM in both of my books. If you want to know how to wield a DMM and: - Know how to properly use it - Know how to put the data you can obtain with it to work - Be the EXPERT - Make $$ Then you absolutely should consider the meager investment in the books. Automotive Wiring and Electrical Systems shows you how to USE the DMM with confidence. Automotive Electrical Performance Projects shows you how to use DMMs to analyze the performance of various circuits, including your charging system. You can read more about both books here - http://www.ceautoelectricsupply.com/wiringbooks.html Keep in mind, these are award winning titles and my first book has sold approximately 25,000 copies to date!
