Hey guys. Last night I was driving and it was going good. I drove for about an hour and coming up a slight hill I started smelling something burn and then after about 15 seconds the FJ40 shut down and died. Lights and radio still worked. I tried to crank it and it wanted to crank but would not crank one revolution. I thought it was the alternator so this morning I went there tried cranking and the same thing. BAttery was at 12.48 volts and I brought a fresh battery with me and installed it and still nothing,. Any ideas? COuld the regulator have gone bad? The strange thing is that I did not see gauges flicker or get wackey so I am unsure if it is regulator. I kind of ruled out alternator as the battery is at 12.48 volts. Any inpu (I hope engine is not seized - it has 82,000 original miles)
