Hey guys,
I'm struggling with an issue. I cranked my bike up yesterday and it ran for about 5 seconds then quit. I hit the starter button again and had nothing. Cycled the ignition switch and kill switch, and no lights or power to anything. I checked and cleaned the connections to the battery, checked the main fuse (it's not blown) and neither are the other fuses. I took the ignition switch off the bike and checked it, there is continuity through the switch. I still have no power through the switch to the bike.
Any help would be appreciated.
78 no power to bike

Assume nothing.Replace that 33 year old dog bone fuse and clean the battery ground wire at the frame.
Use a test light.Probe from the battery post(with the key on)all the way to the coils.
The most common fail point is a good looking dog bone fuse on the starter relay. Here's a schematic if it will help identify wires.If you don't find it quick,let us know,we can direct you to the test procedures and points.

Re: 78 no power to bike
I have replaced the old dogbone fuseblock with a new style ATC blade fuseable link. That was done weeks ago due to a faulty dogbone block. that fuse and contacts are beautiful. I have also taken a razor knife and cleaned all the terminals and wires going to the battery. Am in the process of checking with a meter through the wiring toward the switch. I have just found one wire connection that appears to have broken out of a connector leading from the main wiring harness up to the dash and dummy lights. I can't identify it (Green with Red stripe) It appears like a faded green color but i guess it could be GREY too.

Re: 78 no power to bike
Measuring continuity is OK but the best method in a "no voltage situation " is to use a test light as it provides a load on the circuit being tested.Or use the voltmeter and test with the key ON.
With a "dead"bike,tho only wires to consider are the large red going to the ignition switch and the black leaving it.The rest of the wiring is for the accessories .
I have seen contacts so bad that they measure ohms OK but wont let any current pass.
