1987 or 1988 Suzuki DT55 Electrical Difficulties

[DickJohnson]

My Suzuki DT55 (oil injected) has been in dry dock for about twelve years since my dad passed away. I believe it's an '87 or '88. I don't think it has more than 40 hours running time on it. Recent work performed by myself and by a certified Suzuki mechanic: Carbs cleaned. Impeller replaced. Gear case relubed. New fuel filter. New starter solenoid. New neutral safety switch. New plugs. Oil pump/lines bled. New gaskets. <br /><br />The Suzi mechanic told me they "got it running." (I should have had the fella start it when I was there to pick it up) Anyway, when I hook up a charged battery (650 marine cranking...550 cold cranking) and turn the key I get nothing (w/ shifter in neutral). Not even power trim. Making a connection (bridge) with a screwdriver from the wire coming in from the battery that goes into solenoid to the wire going into the starter itself I'm able to determine that electricity is reaching the starter solenoid b/c the starter tries to do what a starter is supposed to do. (I didn't try long enough to allow it to fire. Definitely getting juice, though.) <br /><br />Could there be a bad fuse preventing me from starting the engine with the key?

Hi,<br />I belive there is at least 3 fuses on a DT55(one 10 Amp and two 25 Amp) that can maybe have something to do with this problem. A wiring diagram will help here... but look for two of the 25 Amps fuses under the cowl, I'm not sure where to look for the 10 Amp fuse. I had a Suzuki DT65 (1991) before and DT55 is basically a DT65 except other carburators. I know I have seen fuses under the cowl on the DT65 I had.<br /><br />/Bo

I've seen the wiring diagram for the engine and found two fuses, I think the 25s. I think they're in what I've heard called the power pack, (for now I'll assume that is the cowl to which you referred in your posting.) Thanks for the info, Bo. I'll get to what I can this evening and see what happens.

After painstakingly following the battery wire from the remote shifter box to the starter relay I found a factory splice that corroded and replaced it and i'm getting juice everywhere now!! Thanks for everyone's input.
