Tuscan drainig battery ????

[RodMod]

Afternoon,

I went to use the Tuscan a few weeks ago (while not in use its plugged in via the trickle charger) and it was completely dead. After checking the battery I noticed it had been on there for 4 years so thought must be the issue. However I fitted a new battery plugged the trickle charge back in and today its totally dead again?

If anyone has any ideas of where I should start looking for possible shorting or earthing out problems or anything similar has happened to you I would love some help or ideas please.

Thanks in advance.

Rod.
