you guys where correct I checked the voltage at the battery in the past but it is low now when cranking and the my tec software is showing it drop to 10.5 but it bounces around 10.5 and 12.6 fast once it stays over 11.75 for a second while cranking there is crank signal. If it is on the 55amp start booster and gets up to 14.6 volts it will give a crank signal one second after I turn the key but only three times then it has to get back to 14.6 to get signal again. I have all the fuses out and a new optima deep cycle 870amp battery today. After looking at the trunk mounted battery it has a 0 cable so I added a 2 and added a second but it showed no difference. This is a hard one to solve
