How heavy a load should switches be able to handle when re-wireing my bike?
A. Ignnition switch 30A lights 20A turns if equiped 15A horn 15A Q. I have seen the black stuff oozing out of my sohc coils and I just switched them out no biggy . But I dont know what causes this and does it mean your coils are bad automatically . A. basically that black goo is the insulation around the coils of wire inside the coil case. the coil may function for quite a while even in its disgusting state but it is on its way out. grab a set somewhere while you have been warned that they are expireing, the problem is likely being caused by heat and or a bad ground or secondary wires. Check for resistance (Ohms) on the secondary wires (Lil wires to the coil) I’m not aware what a ‘good’ reading should be, but you can find out by measuring Ohms on a piece of new wire of the same gauge and length… if the orignal wire has too much resistance the coil will run way hot and melt. Also, check your polarity, most coils will run backwards, but they drop in efficiency quite a bit and wear out
