I’m currently fitting a new 215BD Exalto motor to my boat. The Doga it’s replacing has 3 wires, switched live, permanent live and negative, I assume the permanent live is self park. If I wire the permanent live to park on the Exalto motor it blows the fuse. The wiper works on the switched live but if the blade encounters an obstruction the fuse blows (5a fuse as per instructions). As I only have an on/off switch the ‘fast wipe’ wire is not connected. It’s now starting to mess with my head, anyone any idea of the problem or do I have a faulty motor?

I don't know but my thought would be that the positive should not be connected to both the run and park terminals at the same time. You said if you connect the switched positive wire to the run terminal it works. If you then switch off mid cycle then remove the positive wire and connect it to the park terminal and switch on again, does the motor run to finish the cycle and park? If so, you need a switch that swaps between run and park. If not, ignore this thought ?

If I connect the permanent live to the run terminal the motor runs regardless of switch position. If the run terminal is attached to the switched live it works as expected. If the park terminal is then attached to the permanent live the fuse blows. When I got the motor the default angle of swipe was 40^ I changed this to 110^ which was too wide, when the wiper hits the window frame the fuse blows which strikes me as odd. I’ve reduced the wipe angle to 90^ and will try again tomorrow, without the arm attached the motor runs ok without the park wire attached.
I’ve never had 8 blown fuses before ?

Just to clarify, there are 2 positive wires, one switched and one permanent live.

So if you disconnect power to the run terminal and then connect the permanent live to the park terminal does the fuse blow?
 
Seem to have overcome the problem by attaching the ‘fast wipe’ wire to the switched live and leaving the ‘slow wipe’ wire unconnected. I wouldn’t say it’s a fast wipe but it does work, self parks and hasn‘t (yet) blown the fuse. Perplexed by this but fingers crossed it stays working ?

That's good you got it sorted (ish!) ?
Did you keep the single wiper arms or go pantograph?

Pantograph, I tried an expensive bodge with some generic pantograph arms which didn’t work ?The Doga UK agent is as much use as a chocolate teapot so I’m replacing both motors with Exalto which are pantograph friendly and fit pretty well in the space ?
 
Madness, you'd think it would be quite easy to work out which combination of motors, arms and wipers would fit but seems not.

I looked into it a while back then realised it would be best part of a hell of a lot of money just to sort out the wipers and I didn't know if it was going to work before putting it all together. Sure it was going to be about £600 or something.
Then I ended up needing a new dinghy and radar scanner so I got those instead...

Wipers work ok now with the 60cm long blades so will leave as they are for now.

It’s cost me £300 for new motors and pantograph arms. I buggered up one of the Doga motors whilst trying to bodge so reckoned I might as well replace both. Another ‘to do’ ticked off the list anyway ☑️
 
Ah nice one... That's less than I thought it might be.
For £300 I would be very interested in the specific parts you fitted in case I fancy swapping mine over next year!
Cheers
 
PS did you have to buy a new wiper switch/controller or was it ok to wire up the new motors to the standard on/off rocker switch on the dash?

I used the existing on/off switch and cabling, which probably caused my fuse problems. The annoying thing is that Doga make the relevant parts. I emailed the UK agent requesting a quote for the specific part numbers who referred me back to Doga Spain! When I asked if there was anyone in the UK retailing these they asked which parts I needed!!? Easier to rip them out and start again.

Nightmare... I think i understand :)

So you can use the existing switches at a push like you did (but it's a slight bodge).

Or ideally you would use new controllers... Is it one of these? It came up when i googled the motors.

You could change the controller but a) expensive and b) you’d need to run all the cabling which would be a real ball ache. I just crimped spade connectors onto the motor wires and plugged into the existing wiring.
BTW, the Exalto comes with a wipe angle of 40^ as default. Easy enough to change once you read between all the lines in the instructions and draw your own conclusions. 90^ seems to be spot on.
