Was driving down the road when instrument cluster and clock on radio started to blink simultaneously bright to dim now truck doesn't turn over
Either the starter or the alternator
Have the battery fully recharged and checked, make sure the battery cable ends and nice and clean, none of that black corrosion, make sure all of the cable connections are clean and tight, then check for blown fuses, if none are found see if the truck starts, if it does then check the alternator output, it should be between 13.8 to 14.2 volts. It is really hard to say why you dash did what did unless the voltage was just getting too low to maintain all of the equipment at that time. HTH
I was running a power inverter plugged into the cigar light power point @the time, checked fuses and yes some were blown. Replaced the blown fuses with the proper amp fuses still nothing battery has full charge turn key and nothing but a click noise from the kik pannel fuse box
Sounds like a weak power supply, have you checked the mains in the power distribution box under the hood? Also check the battery cables, make sure they are clean, none of the black corrosion, if that check good then you will need to perform a voltage drop test on the cables themselves.
Mains???? Power distribution box???? What are these? ?? And how do I check them???
And what is a voltage drop test??
Power distribution box is under the hood, it is labeled as such. Voltage drop is hooking up a volt meter to your battery cables at the battery and try to crank it see what the voltage is then attach then to when they are connected to the starter and do the same thing if the voltage is not the same then you have a bad cables.
You check the mains with a test light or you can remove they one at a time and test for continunity with an ohm meter.
