Thank you both for the replies and patience. I have ordered a manual and a new key switch along with a seat switch. I don't want to keep bypassing in case of forgetting I have something bypassed I'm going to take Bert's advice and just fix everything I know is wrong right and go from there before I burn it to the ground. Many thanks
Do that and you will be answering the EZ series posts like a pro.
When I bought the repair run a decade ago I was very conversant with petrol engines but not with mowers mechanically
I struggled for a few years till I got a JD 455 ( diesel engine ) to fix so I bought the JD technical manual
Not only did I manage to repair the mower ( 3 times ) but I was then confident that I was servicing it properly ( also 3 times ) so the $ 175 manual made me over $ 2000 , a good investment .
Having found that so good I bought the 100 series manual and quickly became the guru of 100 series and again it made me a lot of money and because most Husqvarna tractors & clones are almost identical I became proficient servicing & repairing them as well .
Mower wiring is pretty basic if you split it down to individual circuits and the JD manual does exactly that .
Plus it tells you where every switch is , what every wire at every plug does + how and where to do the tests with nothing more than a multimeter or test lamp .
You will curse the dealer for not trying to sell you one with the mower .
I love the EZ series, they are very well made and very robust .
The only design failure I have found was the lift arm breaking away from the rod ( axel if you like ) but in oth cases that was on a mower that was being used by contractors every day, well above & beyond its design .
