Bob car 863 intermittent power to computer

[Ocaf04]

Everything else has constant power besides the computer. Turns on, turns off. Ignition relay is clicking. Been trying to track down the problem for 2 days !

OR LOOSE TERMINALS

OR LOOSE TERMINALS

Battery is good, terminals are tight

 

[polishpete]

what happen when u put cables on it
so when u turn key no start right

 

[polishpete]

All tight there. If i jump the starter the machine cranks but won't start because of the fuel shut off.

right i forgot i could jump the relay to start it
so the injectors fire seems like a loose conection somwhere and
the fusees and relays all pushed in

All fuses are good all relays are good. Gets 11.8v at the connector to the computer. But not constant

or other option is to run a jumper from battery to the start panel positive
wire and possibly ground whats happening is u loosing power to the start panel

 

[polishpete]

its the panel thats going bad but question is whicj one where its key or code could be causeing
the other one to blink

 

[polishpete]

jump the ignition relay and jup the starter will start but other wise one of the panels
is going bad prabbly due to water

isocell.com contact them they rebuild

watched the video and the on and off is steady,like it is powering up and the computer does not like what it sees and trys to reboot or maybe a thermal overload switch is kicking in and out? I would not think that it is not a battery source problem with it ,like the panel has a loose connection. but to verify if you could find the hot that feeds the panel, put a volt meter on it and see if it does the same pulsing. weird

moving the meter around in various places on the machine might help to see where you are getting or not getting the voltage swings.
