Engine Turns But No/random Spark

Hey All, I'm trying to get a 2001 Thunderbird running that has been sitting for a year. I'm having trouble getting the spark plugs to fire. The engine cranks but it'll only spark randomly every couple of seconds. I've tested each coil and they all are doing the same occasional random spark. I've checked all the connectors and they seem good except for some kind of grease in a few of them. Is that a standard thing on Triumphs?

Anyone had this problem before. I'm guessing the ignition pickup sensor is malfunctioning but wanted to see if anyone else has had a similar issue before buying a new one. I tested the resistance on the sensor and got with in spec. Can't remember the exact number right now, but it was something like 585.

 

Are you asking about from the coil where the wire connects or the other end of the wire? The connection to the coil looks fine but I don't know where the end of the wires are. They disappear into the wiring harness.

 

I don't know what ground connections y'all are talking about. There is a ground from the battery to the engine but everything else connects into the wire harness as far as I can tell. Is there a ground somewhere under the cover where the crank sensor is?

 

Well I ordered a new ignition pickup from Squaredeals. They sent me a confirmation a few days ago with a tracking number but no tracking has updated. I'm wondering if they are out like mpllineman said and haven't told me yet. Anyway, I went to remove the old one and my size 30 torx bit seemed pretty loose in the bolt and my 40 is way to big. Do y'all know if I need a specialty tool to get these bolts out?

 

Alright. Finally got the part and the right sized Torx bit. I swapped the ignition pickup and still no spark. Is there anything in the kill switch housing that would cause the coils not to fire? I feel like the starter button is a little temperamental and I’ll occasionally get a spark right when I let off the button. Is there something that needs to be grounded through the handlebars in the kill switch housing? The previous owner swapped the handlebars. Does anyone have a wiring diagram for a 2001 Thunderbird?

 

Alright so I just discovered that as soon as I turn the key on the voltage on the battery drops to about 7 volts from 12. I have the headlight removed so I don't know what would be drawing so much power. It climbs back up to 10+volts as soon as I turn the key off and slowly keeps climbing. The battery is only a few months old and I haven't even been using it. When I'm working on electrical stuff I have a big 30amp battery that I use so I don't kill the battery that the bike actually uses.

So what could be causing such a huge drop in voltage?

 

I think you might be right. I hooked up my big battery again and it didn't drop like the other one did.

So the kill switch and starter button seems to be good. I'm trying to trace the wiring back through the harness but am having a hard time. What else could it be? I don't think all three coils would crap out at the same time. I know the ECU is still a possibility but I'm trying to test everything before suggesting my guy to buy a new one.

Does anyone have a link to a wiring diagram?!
