Short-circuit. Always the main reason check it. It works 556? Do you measure a frequency on the 9. foot?
+E, -E, virtual '0'. These values are properly? Join the coil to the electronics first, switch it on then. Oscillates the coil? The oscillator circuit does not live according to me, IRF lets the current across simply. Is IRF getting warm?
Check tying up the rectifiers.

i have 12vdc from buttry
my 556 freq without coil is 320 hz
i think my circit have shor-circuit. but i cant find it
when i conect coil in circuit my irf840 is hot
Hi hadi-dindar
VD17=LED power
VD16=LED low batt.
-the error 1- bad batt.
2- bad In the following components(Check and test) -There must be sound, whether there is a coil or not(Tested and check T9)
best time
