fuso 310 fish finder

[Idlerboat]

I have a FUSO 310 fish finder that I inherited with the boat. The unit powers up with the screnn and basic graphics. After inspection it seems that the unit is devided into two boards inside. One board looks like it is a control and graphics board and the other looks like the tansducer driver. The transducers themselves are sealed units but visual inspection of them shows no sign of damage. The problem apears to be a blown resistor (R5) on the transducer board, because its good and crispy I cant tell what value it was and hence cant replace it to try and trouble shoot further. Needles to say I have been told that FUSO has gone out of business. What I need is a circuit diagram of this unit, or for some kind soul to take the back off their unit and look for the resistor marked (R5) on the smaller circuit board and email me the value. (If you don,t know the colour stripe scheme of resistors just tell me the four colours in order.) Its not a newer unit but repacement is a bit costly. And I am a PBO!!

moto :I try 2 yot 4 nix.
