Another thing you may want to check, does this truck have the older style Regen heatsink? Is the 1A contactor missing and the regen mounted right above the caster? Check the com cable from the regen assy to thepower card.
Check your static strap. Remember that the reach truck and the orderpicker static strap assy; look identical, but the impregnated resistors are different, also Edward is right about isolateing the battery first and putting it outside the truck under power. Is the firm ware updated? If not you may want to try a new VFC with updated firmware.
thank you for information on battery does anyone have a opinion on intermitent f4 shoud i replace vfc card than you
as far as "checking the battery", first, pull the battery from the machine, and in compliance with local regulations, get all the battery corrosion from the truck, and replace ANY power cables that have been resting in that corrosion, or that have ANY damage to their insulation. Fully charge the battery, than test -each- cell with a volt meter and record each cell's voltage. check each cell's specific gravity with a good temparature compensated hydrometer. if there is more than a 10% difference between any 2 cells voltage or specific gravity readings, then you have a battery problem. next you would "load test" the battery using a volt meter and the hydraulic lifting motor stalled at the top of it's stroke (but never stall more than 3 seconds), a voltage drop of 10% or more is also a sign of a bad battery.
can anyone help intermittant f4 icheck snubber componants and best way to check battery
can anyone help i was going to check snubber componants and best way to check battery
yes i did ck short to frame i had to replace drive motor it had 2 thousand ohms from case to.power lugs.and i also changed battey.But istill have problem turn on key f4 turn off and back on maybe 5times then machine will work.i have manual.can any one tell me anything more to try
How's the battery?
Intermittant faults with Raymonds are 'normally' tied with poor battery conditions. Hvae you checked for shorts to frame, voltage under load, etc?
