Electrical issues

Hi All,

I am currently running into some electrical issues with my vehicle. I drove the vehicle not long ago and decided to take it out the other day. To my surprise the batteries were dead. Being they are only a year old I took them to get tested and only one of them had actually failed. I re-installed both batteries (vehicle has a dual battery setup) and went to start the vehicle. Still there was nothing but a click. I thought to myself well that has to be the solenoid or the starter and could have been the cause for the battery drainage. I then went and purchased a started and solenoid as they were pretty dated. Once I put those on still nothing but a click noise. I now noticed that it was coming from the relay on the firewall. I then replaced that thinking it may have been dated. Went to start the vehicle and still got the clicking noise. I then thought well maybe the key lock is bad. I then ordered a new key lock and installed it. I still got nothing but the click from the relay. What I do not understand is when you put the key in the run position you can hear the fuel injection cut on (this vehicle has a fuel injected 360). Once you go to start it there is nothing but a single click from the relay. At this point I am running out of options. I believe the CJ's do not have a clutch override so I do not think that is an issue. I would assume that the vehicle is getting power to the relay but it is not transferring it to the starter. Just so everyone knows this vehicle is equipped with a Painless wiring harness. Does anyone have any ideas what else it may be? At this point I am stuck. I would hate to get it towed to the shop when I can fix it myself. Any information would be greatly appreciated.
Do you
have the same problem?

Check the fusible links on starter solenoid. See picture they should have twelve volts both sides. Not Painless uses a fusible link though. I am sure you can go online and find their schematic as that is all a shop would do. One thing to check is to check for a good ground from battery to body as well as batter to engine and engine to body. What I am sending is factory hookup for fusible link.
