I have a 1984 subaru brat. Rebuilt engine, new distributor, new coil pretty much all new. No matter what i do when i turn the key i get no interior power.... The thing cranks with no spark and all that works is my hazard lights! If i run a jumper wire from the + on the battery to the + on the coil i have power on everything and weak spark and not the full voltage i need, and the power is constant even when the key is off EVERYTHING stays illuminated and on inside. Could someone please tell me what i need to look for here? i am completely out of ideas. I know its gotta be a wiring problem but i just dont know where to begin.
Second question. What is the yellow and white wire that runs from the coil to the computer, whats its purpose?
Thanks in advance
